usb: enable usb port device's async suspend.
This patch is to set power.async_suspend for usb port in order
to allow it to be suspended and resumed asynchronously during
system sleep transitions.
The power.async_suspend flag is also set for devices that don't have
suspend or resume callbacks, because otherwise they would make the
main suspend/resume thread wait for their "asynchronous" children
(during suspend) or parents (during resume), effectively negating the
possible gains from executing these devices' suspend and resume
callbacks asynchronously.

This effects of this bug are minimal. The hub driver may end up doing

btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
head of the list again. But because we don't delete the first inode that it

usb: dwc3: gadget: change HIRD threshold to 12
First of all, that 28 value makes no sense as
HIRD threshold is a 4-bit value, second of all
it's causing issues for OMAP5.
Using 12 because commit
cbc725b3 (usb: dwc3:
keep default hird threshold value as 4b1100)
had the intention of setting the maximum allowed
value of 0xc.
Also, original code has been wrong forever, so
this should be backported as far back as
possible.

USB: EHCI: fix build error in ehci-mxc
This patch (as1643b) fixes a build error in ehci-hcd when compiling for
ARM with allmodconfig:
drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition

drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition
The fix is to convert ehci-mxc over to the new "ehci-hcd is a library"
scheme so that it can coexist peacefully with the ehci-platform
driver. As part of the conversion the ehci_mxc_priv data structure,
which was allocated dynamically, is now placed where it belongs: in
the private area at the end of struct ehci_hcd.

ALSA: hda - Fix inconsistent pin states after resume
The commit [
26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a
module parameter] introduced the polling jack detection code, but it
also moved the call of snd_hda_jack_set_dirty_all() in the resume path
after resume/init ops call. This caused a regression when the jack
state has been changed during power-down (e.g. in the power save
mode). Since the driver doesn't probe the new jack state but keeps
using the cached value due to no dirty flag, the pin state remains
also as if the jack is still plugged.
The fix is simply moving snd_hda_jack_set_dirty_all() to the original
position.
