When code to manipulate the command register was refactored from
xhci_run() to xhci_start(), a debugging statement was left behind that no
longer applies. Remove that statement.

This patch (as1392) fixes a bug in uhci-hcd: The start_rh() routine is
supposed to be called with the private spinlock held. If an IRQ comes
in at just the wrong time, the driver will think the controller has
died when in fact it simply hasn't start yet.
The patch also addresses some issues that may prevent an URB from
being unlinked after the controller has stopped. This is an abnormal
occurrence (ordinarily the controller stops only when the entire bus
is suspended and hence there are no active URBs), so the pathways
haven't gotten much testing. These two changes may be a little more
than is strictly necessary, but clearly they won't hurt.

This patch (as1391) fixes a problem that can occur when USB host
controller hardware is hot-unplugged. If no interrupts are generated
by the unplug then the HCD may not realize that the controller is
gone, and the subsequent unbind may hang waiting for interrupts that
never arrive.
The solution (for PCI-based controllers) is to call the HCD's
interrupt handler at the start of usb_hcd_pci_remove(). If the
hardware is gone, the handler will realize this when it tries to read
the controller's status register.

This patch (as1390) fixes a problem that crops up when a UHCI host
controller is unbound from uhci-hcd while there are still some active
URBs. The URBs have to be unlinked when the root hub is unregistered,
and uhci-hcd relies upon root-hub status polls as part of its
unlinking procedure. But usb_hcd_poll_rh_status() won't make those
status calls if hcd->rh_registered is clear, and the flag is cleared
_before_ the unregistration takes place.
Since hcd->rh_registered is used for other things and needs to be
cleared early, the solution is to add a new flag (rh_pollable) and use
it instead. It gets cleared _after_ the root hub is unregistered.
Now that the status polls don't end too soon, we have to make sure
they also don't occur too late -- after the root hub's usb_device
structure or the HCD's private structures are deallocated. Therefore
the patch adds usb_get_device() and usb_put_device() calls to protect
the root hub structure, and it adds an extra del_timer_sync() to
prevent the root-hub timer from causing an unexpected status poll.
This additional complexity would not be needed if the HCD framework
had provided separate stop() and release() callbacks instead of just
stop(). This lack could be fixed at some future time (although it
would require changes to every host controller driver); when that
happens this patch won't be needed any more.

This patch (as1389) fixes some errors in the failure pathway of
usb_add_hcd(). The actions it takes ought to be exactly the same as
those taken by usb_remove_hcd(), but they aren't.
In one case (removal of the usb_bus_attr_group), the two routines are
brought into agreement by changing usb_remove_hcd(). All the other
discrepancies are fixed by changing usb_add_hcd().

This change addresses the following situation:
- Thread A acquires the rwsem for read
- Thread B tries to acquire the rwsem for write, notices there is already
an active owner for the rwsem.
- Thread C tries to acquire the rwsem for read, notices that thread B already
tried to acquire it.
- Thread C grabs the spinlock and queues itself on the wait queue.
- Thread B grabs the spinlock and queues itself behind C. At this point A is
the only remaining active owner on the rwsem.
In this situation thread B could notice that it was the last active writer
on the rwsem, and decide to wake C to let it proceed in parallel with A
since they both only want the rwsem for read.

Previously each waiting thread added a bias of RWSEM_WAITING_BIAS. With
this change, the bias is added only once to indicate that the wait list is
non-empty.
This has a few nice properties which will be used in following changes:
- when the spinlock is held and the waiter list is known to be non-empty,
count < RWSEM_WAITING_BIAS <=> there is an active writer on that sem
- count == RWSEM_WAITING_BIAS <=> there are waiting threads and no
active readers/writers on that sem

In __rwsem_do_wake(), we can skip the active count check unless we come
there from up_xxxx(). Also when checking the active count, it is not
actually necessary to increment it; this allows us to get rid of the read
side undo code and simplify the calculation of the final rwsem count
adjustment once we've counted the reader threads to wake.
The basic observation is the following. When there are waiter threads on
a rwsem and the spinlock is held, other threads can only increment the
active count by trying to grab the rwsem in down_xxxx(). However
down_xxxx() will notice there are waiter threads and take the down_failed
path, blocking to acquire the spinlock on the way there. Therefore, a
thread observing an active count of zero with waiters queued and the
spinlock held, is protected against other threads acquiring the rwsem
until it wakes the last waiter or releases the spinlock.

This is in preparation for later changes in the series.
In __rwsem_do_wake(), the first queued waiter is checked first in order to
determine whether it's a writer or a reader. The code paths diverge at
this point. The code that checks and increments the rwsem active count is
duplicated on both sides - the point is that later changes in the series
will be able to independently modify both sides.

Allow device probing to recognise the Fintek F71808E.
Sysfs interface:
* Fan/pwm control is the same as for F71889FG
* Temperature and voltage sensor handling is largely the same as for
the F71889FG
- Has one temperature sensor less (doesn't have temp3)
- Misses one voltage sensor (doesn't have V6, thus in6_input refers to
what in7_input refers for F71889FG)
For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.

Fix two errors in hotplug. One is for hotplug notifier. The other is
unnecessary driver unregister. Because even none of online cpus supports
coretemp, we can't assume new onlined cpu doesn't support it either. If
related driver is unregistered there we have no chance to use coretemp
from then on.

These are caused by checkpatch incorrectly parsing its internal
representation of a statement block for struct's (or anything else that is
a statement block encapsulated in {}'s that also ends with a ';'). Fix
this by properly parsing a statement block.
An example:
+struct dummy_type dummy = {
+ .foo = "baz",
+};
+EXPORT_SYMBOL_GPL(dummy);
+
+static int dummy_func(void)
+{
+ return -EDUMMYCODE;
+}
+EXPORT_SYMBOL_GPL(dummy_func);
WARNING: EXPORT_SYMBOL(foo); should immediately \
follow its function/variable
#19: FILE: dummy.c:4:
+EXPORT_SYMBOL_GPL(dummy);
The above warning is issued when it should not be.

As explained in Documentation/timers/timers-howto.txt, msleep's of < 20ms
may sleep for as long as 20ms. Caller's of msleep(1) or msleep(2), etc
are likely not to expect this quirky behavior - warn them.

When possible, sleeping is (usually) better than delaying; however, don't
bother callers of udelay < 10us, as those cases are generally not worth
the switch to usleep

Make error message say 'ERROR: do not initialise globals to 0 or NULL'
rather than 'ERROR: do not initialise externals to 0 or NULL'. Makes more
sense in the context since there is an extern keyword in C and that is a
global declaration within the scope of the current file.

I've got a false positive when spaces are present at the beginning of a
line.
So I add this check, obviously excluding to check the lines in the middle of
comments.
For instance this code passes the checkpatch test:
+struct davinci_mcbsp_data {
+ unsigned int fmt;
+ int clk_div;
+};
+
+static struct davinci_mcbsp_data mcbsp_data;
Where, before the string "int clk_div", I have 4 spaces (\040
ascii character).
With v2.6.34 scripts/checkpatch.pl script I get:
scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch
total: 0 errors, 0 warnings, 201 lines checked
0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch has no obvious style
problems and is ready for submission.
That is not correct. Instead with the proposed patch I get:
scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch
WARNING: please, no space for starting a line,
excluding comments
#63: FILE: sound/soc/davinci/davinci-i2s.c:165:

WARNING: please, no space for starting a line,
excluding comments
#95: FILE: sound/soc/davinci/davinci-i2s.c:406:
+ return 0;$
total: 0 errors, 2 warnings, 201 lines checked
That is correct.

Getting and putting arrays of pointers with flex arrays is a PITA. You
have to remember to pass &ptr to the _put and you have to do weird and
wacky casting to get the ptr back from the _get. Add two functions
flex_array_get_ptr() and flex_array_put_ptr() to handle all of the magic.
