The WM8978 codec from Wolfson Microelectronics is very similar to
wm8974, but is stereo and also has some differences in pin configuration
and internal signal routing. This driver is based on wm8974 and takes
the differences into account.

vmalloc: remove BUG_ON due to racy counting of VM_LAZY_FREE
In free_unmap_area_noflush(), va->flags is marked as VM_LAZY_FREE first, and
then vmap_lazy_nr is increased atomically.
But, in __purge_vmap_area_lazy(), while traversing of vmap_are_list, nr
is counted by checking VM_LAZY_FREE is set to va->flags. After counting
the variable nr, kernel reads vmap_lazy_nr atomically and checks a
BUG_ON condition whether nr is greater than vmap_lazy_nr to prevent
vmap_lazy_nr from being negative.
The problem is that, if interrupted right after marking VM_LAZY_FREE,
increment of vmap_lazy_nr can be delayed. Consequently, BUG_ON
condition can be met because nr is counted more than vmap_lazy_nr.
It is highly probable when vmalloc/vfree are called frequently. This
scenario have been verified by adding delay between marking VM_LAZY_FREE
and increasing vmap_lazy_nr in free_unmap_area_noflush().
Even the vmap_lazy_nr is for checking high watermark, it never be the
strict watermark. Although the BUG_ON condition is to prevent
vmap_lazy_nr from being negative, vmap_lazy_nr is signed variable. So,
it could go down to negative value temporarily.
Consequently, removing the BUG_ON condition is proper.
A possible BUG_ON message is like the below.

ASoC: Support turning off bias when the CODEC is idle
Currently ASoC always maintains the bias of the CODEC while the system
is active. With older mobile CODECs this is required since the outputs
are referenced to a non-zero voltage and enabling or disabling this
voltage without audible pops or clicks in the output takes too long to
do when starting or stopping audio.
As a result of features such as ground referenced outputs and class D
speaker drivers current generation devices are able to power on and off
much more quickly without these system level issues so provide a new
flag idle_bias_off in snd_soc_codec which will cause the core to turn
off the CODEC bias. The distinction between STANDBY and OFF is still
maintained. This is partly for consistency but also allows for
potential future extensions such as per-machine overrides or deferring
the bias removal.

USB: fix usbstorage for 2770:915d delivers no FAT
Resolves kernel.org bug 14914.
Remove entry for 2770:915d (usb digital camera with mass storage
support) from unusual_devs.h. The fix triggered by the entry causes
the file system on the camera to be completely inaccessible (no
partition table, the device is not mountable).
The patch works, but let me clarify a few things about it. All the
patch does is remove the entry for this device from the
drivers/usb/storage/unusual_devs.h, which is supposed to help with a
problem with the device's reported size (I think). I'm pretty sure it
was originally added for a reason, so I'm not sure removing it won't
cause other problems to reappear. Also, I should note that this
unusual_devs.h entry was present (and activating workarounds) in
2.6.29, but in that version everything works fine. Starting with
2.6.30, things no longer work.

[ 427.916699] Call Trace:
The problem is caused by a mismatch between the USB core's view of the
device state and the USB device and xHCI host's view of the device state.
After the device reset and re-configuration, the device and the xHCI host
think they are using alternate setting 0 of all interfaces. However, the
USB core keeps track of the old state, which may include non-zero
alternate settings. It uses intf->cur_altsetting to keep the endpoint
sysfs files for the old state across the reset.
The bandwidth allocation functions need to know what the xHCI host thinks
the current alternate settings are, so original patch set
intf->cur_altsetting to the alternate setting 0. This caused duplicate
endpoint files to be created.
The solution is to not set intf->cur_altsetting before calling
usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a
new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use
alternate setting 0 as the currently installed alternate setting.

USB: add missing delay during remote wakeup
This patch (as1330) fixes a bug in khbud's handling of remote
wakeups. When a device sends a remote-wakeup request, the parent hub
(or the host controller driver, for directly attached devices) begins
the resume sequence and notifies khubd when the sequence finishes. At
this point the port's SUSPEND feature is automatically turned off.
However the device needs an additional 10-ms resume-recovery time
(TRSMRCY in the USB spec). Khubd does not wait for this delay if the
SUSPEND feature is off, and as a result some devices fail to behave
properly following a remote wakeup. This patch adds the missing
delay to the remote-wakeup path.
It also extends the resume-signalling delay used by ehci-hcd and
uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use
for non-remote-wakeup resumes). The extra time appears to help some
devices.

if they are then it fails the root-hub suspend with -EBUSY.

USB: EHCI: fix handling of unusual interrupt intervals
This patch (as1320) fixes two problems related to interrupt-URB
scheduling in ehci-hcd.
URBs with an interval of 2 or 4 microframes aren't handled.
For the time being, the patch reduces to interval to 1 uframe.
URBs are constrained to have an interval no larger than 1024
frames by usb_submit_urb(). But some EHCI controllers allow
use of a schedule as short as 256 frames; for these
controllers we may have to decrease the interval to the
actual schedule length.
The second problem isn't very significant since few devices expose
interrupt endpoints with an interval larger than 256 frames. But the
first problem is critical; it will prevent the kernel from working
with devices having interrupt intervals of 2 or 4 uframes.
