msm: ipc: Serialize SMD XPRT CLOSE and OPEN events

When a remote subsystem resets, IPC Router's SMD XPRT Layer queues a CLOSE
event. When the concerned subsytem powers up and the channel is reopened,
SMD XPRT Layer queues a OPEN event. When the remote subsytem resets and
powers up quickly, the following race condition exists:
a) IPC Router is scheduled out while handling the CLOSE event, leaving a
   stale XPRT
b) IPC Router's SMD XPRT Layer queues a OPEN event
c) IPC Router's SMD XPRT Layer reads a HELLO message, finds a stale
   XPRT and queues a DATA event on the stale XPRT
This race condition causes a kernel panic.

Fix this race condition by not handling any other SMD XPRT event until
the CLOSE event is complete.

wcnss: Add API to expose the IRIS XO mode set

IRIS XO mode can be configured thru module parameter; and it can also
be auto detected. Add an API to expose the IRIS XO mode set. WLAN driver
can use this API for it's XO specific operation.

msm_fb: display: Fix interleaved 422 input format register settings

Check to update chroma sample information in source format register is
based on fetch plane value, which does not take into account for
interleaved 422 input format. Remove this check and set chroma sample
values for RGB formats as well.

msm: camera: Handle ioctls issued on vfe subdevice properly

In case vfebase is not set by the time ioctl is issued on the
vfe subdevice, it might lead to kernel panic if the arguments
of the ioctl are not set properly. Now handling these ioctls
before checking for vfebase will remove the possibility of a
kernel panic.

usb: gadget: composite: Fix a bug in delayed status handling

The SET_CONFIGURATION control request's status phase is delayed
till the new config change is handled by the file-storage thread.
If the cable is disconnected or the bus is reset before the
previous config is handled, then composite driver is not notified
about the delayed status.  As a result of which, the delayed_status
field of composite device structure remains non-zero.  The status
phase of next SET_CONFIGURATION control request is not sent.
This makes the gadget unusable.

Calling usb_composite_setup_continue() after the disconnect or reset
does not make any sense.  If the host sends another control request
before the status phase of the previous control request is sent, the
delayed_status must be reset to zero.  This is not straight forward
as the UDC handles some control requests without delegating them to
the composite driver.  A simple fix would be resetting the delayed
status value after the disconnect/reset.

msm: bam_dmux: trigger modem subsystem restart in case of timeout

If bam_dmux times out waiting for a power collapse protocol response from
the modem, bam_dmux assumes the modem has crashed and will disable itself
until the subsystem restart callback is triggered.

Change the behavior in bam_dmux to request that the modem subsystem
restarts regardless of its current state so that the restart callback is
always triggered.
