ASoC: Intel: Restore Baytrail ADSP streams only when ADSP was in reset

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.

__generic_file_write_iter(): fix handling of sync error after DIO

If DIO results in short write and sync write fails, we want to bugger off
whether the DIO part has written anything or not; the logics on the return
will take care of the right return value.

fix copy_tree() regression

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.

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.

carl9170: fix sending URBs with wrong type when using full-speed

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.
