The driver assumes that endpoint 4 is always an interrupt endpoint.
Unfortunately the type differs between high-speed and full-speed
configurations while in the former case it is indeed an interrupt
endpoint this is not true for the latter case - here it is a bulk
endpoint. When sending URBs with the wrong type the kernel will
generate a warning message including backtrace. In this specific
case there will be a huge amount of warnings which can bring the system
to freeze.
To fix this we are now sending URBs to endpoint 4 using the type
found in the endpoint descriptor.
A side note: The carl9170 firmware currently specifies endpoint 4 as
interrupt endpoint even in the full-speed configuration but this has
no relevance because before this firmware is loaded the endpoint type
is as described above and after the firmware is running the stick is not
reenumerated and so the old descriptor is used.

====================
Netfilter fixes for net
The following patchset contains fixes for your net tree, they are:
1) Unitialize the set element key and data from the commit path,
otherwise this leaks chain refcount if the transaction is aborted,
reported by Thomas Graf.
2) Fix crash when updating chains without no counters in nf_tables,
this slipped through in the new transaction infrastructure, reported
by Matteo Croce.
3) Replace all mutex_lock_interruptible() by mutex_lock() in the Netfilter
tree, suggested by Patrick McHardy. This implicitly fixes the problem
that Eric Dumazet reported in: http://patchwork.ozlabs.org/patch/373076/
4) Fix error return code in nf_tables when deleting set element in
nf_tables if the transaction cannot be allocated, from Julia Lawall.

Since 3.14 we had copy_tree() get the shadowing wrong - if we had one
vfsmount shadowing another (i.e. if A is a slave of B, C is mounted
on A/foo, then D got mounted on B/foo creating D' on A/foo shadowed
by C), copy_tree() of A would make a copy of D' shadow the the copy of
C, not the other way around.
It's easy to fix, fortunately - just make sure that mount follows
the one that shadows it in mnt_child as well as in mnt_hash, and when
copy_tree() decides to attach a new mount, check if the last child
it has added to the same parent should be shadowing the new one.
And if it should, just use the same logics commit_tree() has - put the
new mount into the hash and children lists right after the one that
should shadow it.

There is no need to restore and restart PCM streams in case ADSP didn't
reach reset and power off state during system suspend/resume cycle. In that
case stream is still active but paused and firmware doesn't allow allocating
a new stream before paused stream is freed.
ADSP remains active in case suspend sequence didn't go to suspend_late
stage. This can happen when either suspend sequence is aborted by a wakeup
or by letting only devices suspend by "echo devices >/sys/power/pm_test".
Currently stream restoring fails in these suspend cases. Fix this by adding
a flag that indicates is complete stream reinitialization needed or is it
enough to resume paused stream. Flag is set when we know that ADSP reached
suspend_late.
Initial fix to this issue came from Fang Yang. I modified it a little and
forward ported it to top of two other suspend/resume patches from me.

Merge DSP reset and cleanup sequence in sst_byt_pcm_dev_suspend_noirq()
into sst_byt_pcm_dev_suspend_late(). First their order was wrong by first
unloading firmware modules in suspend_late and then taking DSP into reset
in suspend_noirq. Second ACPI has put device into OFF state already during
suspend_late so trying to reset the DSP is a no-op at suspend_noirq stage.
Fix these by moving DSP reset and cleanup into
sst_byt_pcm_dev_suspend_late() before firmware unloading.

If the timer irqs are resumed during device resume it is possible in
certain circumstances for the resume to hang early on, before device
interrupts are resumed. For an Ubuntu 14.04 PVHVM guest this would
occur in ~0.5% of resume attempts.
It is not entirely clear what is occuring the point of the hang but I
think a task necessary for the resume calls schedule_timeout(),
waiting for a timer interrupt (which never arrives). This failure may
require specific tasks to be running on the other VCPUs to trigger
(processes are not frozen during a suspend/resume if PREEMPT is
disabled).
Add IRQF_EARLY_RESUME to the timer interrupts so they are resumed in
syscore_resume().

instead of /proc/self/{mounts,net}"
This reverts commits 344470cac42e and e81324407269.
It turns out that the exact path in the symlink matters, if for somewhat
unfortunate reasons: some apparmor configurations don't allow dhclient
access to the per-thread /proc files. As reported by Jörg Otte:
audit: type=1400 audit(1407684227.003:28): apparmor="DENIED"
operation="open" profile="/sbin/dhclient"
name="/proc/1540/task/1540/net/dev" pid=1540 comm="dhclient"
requested_mask="r" denied_mask="r" fsuid=0 ouid=0
so we had better revert this for now. We might be able to work around
this in practice by only using the per-thread symlinks if the thread
isn't the thread group leader, and if the namespaces differ between
threads (which basically never happens).
We'll see. In the meantime, the revert was made to be intentionally easy.

Currently, the parent interface keeps sending broadcast group join
requests even if p_key index 0 is invalid, which is possible/common in
virtualized environments where a VF has been probed to VM but the
actual P_key configuration has not yet been assigned by the management
software. This creates unnecessary noise on the fabric and in the
kernel logs:
ib0: multicast join failed for ff12:401b:8000:0000:0000:0000:ffff:ffff, status -22
The original code run the multicast task regardless of the actual
P_key value, which can be avoided. The fix is to re-init resources and
bring interface up only if P_key index 0 is valid either when starting
up or on PKEY_CHANGE event.

Commit 05f1dd5 ("block: add queue flag for disabling SG merging")
introduced a new queue flag: QUEUE_FLAG_NO_SG_MERGE. This gets set by
default in blk_mq_init_queue for mq-enabled devices. The effect of
the flag is to bypass the SG segment merging. Instead, the
bio->bi_vcnt is used as the number of hardware segments.
With a device mapper target on top of a device with
QUEUE_FLAG_NO_SG_MERGE set, we can end up sending down more segments
than a driver is prepared to handle. I ran into this when backporting
the virtio_blk mq support. It triggerred this BUG_ON, in
virtio_queue_rq:
BUG_ON(req->nr_phys_segments + 2 > vblk->sg_elems);
The queue's max is set here:
blk_queue_max_segments(q, vblk->sg_elems-2);
Basically, what happens is that a bio is built up for the dm device
(which does not have the QUEUE_FLAG_NO_SG_MERGE flag set) using
bio_add_page. That path will call into __blk_recalc_rq_segments, so
what you end up with is bi_phys_segments being much smaller than bi_vcnt
(and bi_vcnt grows beyond the maximum sg elements). Then, when the bio
is submitted, it gets cloned. When the cloned bio is submitted, it will
end up in blk_recount_segments, here:
if (test_bit(QUEUE_FLAG_NO_SG_MERGE, &q->queue_flags))
bio->bi_phys_segments = bio->bi_vcnt;
and now we've set bio->bi_phys_segments to a number that is beyond what
was registered as queue_max_segments by the driver.
The right way to fix this is to propagate the queue flag up the stack.
The rules for propagating the flag are simple:
- if the flag is set for any underlying device, it must be set for the
upper device
- consequently, if the flag is not set for any underlying device, it
should not be set for the upper device.

Since commit b42261078a91 ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.
So remove the I2C_FUNC_SMBUS_BYTE_DATA functionality check in the driver code.

capacity_now should be assigned after comparing it to design_capacity.
Otherwise warning is printed even when capacity_now before assignment is
equal to design_capacity, making the check useless and "current charge level"
wrong (it should be higher than, not equal to, "maximum charge level", which
is full_charge_capacity):
"battery: reported current charge level (56410) is higher than reported
maximum charge level (56410)."

CA0132 driver tries to reload the firmware at resume. Usually this
works since the firmware loader core caches the firmware contents by
itself. However, if the driver failed to load the firmwares
(e.g. missing files), reloading the firmware at resume goes through
the actual file loading code path, and triggers a kernel WARNING like:
WARNING: CPU: 10 PID:11371 at drivers/base/firmware_class.c:1105 _request_firmware+0x9ab/0x9d0()
For avoiding this situation, this patch makes CA0132 skipping the f/w
loading at resume when it failed at probe time.

If nid 0x15 (Headphone Playback Switch) is in D3 and headphones are
plugged in when the laptop reboots, a pop noise is generated.
Prevent this by keeping nid 0x15 in D0 when headphones are plugged in.

If the laptop is powered on with a jack plugged in, independently on what
is plugged, the jack is treated as a microphone jack.
Initialize the capture source so that by default jacks are treated as
headphones jacks. This will also prevent pop noises on boot in case
headphones are plugged in since setting/unsetting mic-in as input source
causes a pop noise.

The BOSS ME-25 turns out not to have any useful descriptors in its MIDI

variable read-mostly
A sparse warning is generated about
'tlb_single_page_flush_ceiling' not being declared.
arch/x86/mm/tlb.c:177:15: warning: symbol
'tlb_single_page_flush_ceiling' was not declared. Should it be static?
Since it isn't used anywhere outside this file, fix the warning
by making it static.
Also, optimize the use of this variable by adding the
__read_mostly directive, as suggested by David Rientjes.
