There was an unlock missing on the error path.
Also I did a small cleanup by changing ep->dev->lock for just dev->lock.
They're the same lock, but dev->lock is shorter and that's how it is
used for the spin_unlock_irqrestore() call.

Booting latest kernel on my test machine produces a lockdep
warning from the usb_amd_find_chipset_info() function:
WARNING: at /data/lemmy/linux.trees.git/kernel/lockdep.c:2465 lockdep_trace_alloc+0x95/0xc2()

It turns out that this function calls pci_get_device under a spin_lock
with irqs disabled, but the pci_get_device function is only allowed in
preemptible context.
This patch fixes the warning by making all data-structure
modifications on temporal storage and commiting this back
into the visible structure at the end. While at it, this
patch also moves the pci_dev_put calls out of the spinlocks
because this function might sleep too.

This patch (as1458) fixes a problem affecting ultra-reliable systems:
When hardware failover of an EHCI controller occurs, the data
structures do not get released correctly. This is because the routine
responsible for removing unused QHs from the async schedule assumes
the controller is running properly (the frame counter is used in
determining how long the QH has been idle) -- but when a failover
causes the controller to be electronically disconnected from the PCI
bus, obviously it stops running.
The solution is simple: Allow scan_async() to remove a QH from the
async schedule if it has been idle for long enough _or_ if the
controller is stopped.

While decoding a secinfo reply, I store the list of supported sec
flavors on a page accessible through res->flavors. Before reading
each new flavor, I do some math to determine if there is enough
space left on this page, and I break out of my read look if there
isn't. In order to perform this check correctly, I need to use the
address of res->flavors, rather than the address of res.
When this loop was broken early I lied to the caller and told them
that the entire list had been decoded. This could lead to problems
if the caller tries to use any the garbage data claiming to be a
valid sec flavor. I fixed this by using res->flavors->num_flavors
as a counter, incrementing it every time a sec flavor is
successfully decoded.

This reverts commit c191a836a908d1dd6b40c503741f91b914de3348.
It causes known regressions for programs that expect to be able to use
SO_REUSEADDR to shutdown a socket, then successfully rebind another
socket to the same ID.
Programs such as haproxy and amavisd expect this to work.
This should fix kernel bugzilla 32832.

200 GB storage on a GFS2 filesystem.
This result in memory fragmentation and driver receives 18 frags for

For non tso packet, fw drops the tx request, if it has >14 frags.

Commit ce6120cc(ASoC: Decouple DAPM from CODECs) changed the signature of
snd_soc_dapm_widgets_new to take an pointer to a snd_soc_dapm_context instead of
a snd_soc_codec. The call to snd_soc_dapm_widgets_new in jz4740_codec_dev_probe
was not updated to reflect this change, which results in a compiletime warning
and a runtime OOPS.
Since the core code calls snd_soc_dapm_widgets_new after the codec has been
registered it can be dropped here.

The ATAG_BOARDINFO is intended to hand over the information
bd->bi_board_number from u-boot to the kernel.
This piece of information can be used to implement some kind of board
identification while booting the kernel. Therefore it is placed in .initdata

platform_get_irq returns -ENXIO on failure, so !int_irq was probably
always true. Better use (int)int_irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

We can delete the code that checks to see if we're sending an ignored
signal to init because force_sig_info() already handles this case.
force_sig_info() will kill init even if the signal handler is SIG_DFL
and the scenario described in the comment where init might "generate
the same exception over and over again" cannot occur (force_sig_info()
clears SIGNAL_UNKILLABLE to ensure that init will die).
Also, the use of is_global_init() is not correct in the multhreaded
case, as Oleg Nesterov explains,
"is_global_init() is not right in theory, /sbin/init can be
multithreaded. And, this doesn't cover the sub-namespace
inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking
closer I think you can simply remove this code."
It seems this code was copied from arch/powerpc in March 2007 in commit
623b0355d5b1 "[AVR32] Clean up exception handling code"
but the code was deleted from arch/powerpc in November 2009 in commit
a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()"
So catch up with powerpc and delete the bogus code.
