The intent of this patch is to perform a graceful shutdown of target drives even if
volume doesn't exits. Changes done in this patch
1. Removed the check for the presence of volumes before sending down
MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED. Therefore, this RAID action
would be sent if the card is IR Firmware.
2. The MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED is sent even when the
system undergoes suspend (in addition to remove/shutdown which was already
present)

Added a check to identify if mpi_reply is NULL in mpt2sas_ctl_event_callback()
and return without proceeding if it is the case.
Also modified the following functions to return void instead of 0 or 1
as returning those values from events perspective doesn't make sense.
* _base_async_event()
* mpt2sas_ctl_event_callback()
* mpt2sas_scsih_event_callback()

Cards using the wm8775 specify that in their card struct. Those that do not
use it leave the audio_chip field to 0. Unfortunately, the CX88_AUDIO_WM8775
enum is 0 as well, so boards that do not have the wm8775 still try to load
and use that driver. Change it to 1 to fix this.

Commit 1c1d86a1ea ("[media] v4l2: always require v4l2_dev,

It converted most of the drivers using the parent field of video_device
to v4l2_dev field. G2D driver did not set the parent field. Hence it got
left out. Without this patch we get the following boot warning and G2D
driver fails to register the video device.

Commit 76abbdde2d
pwm: Add sysfs interface
causes a kernel oops due to a null pointer dereference on PXA platforms.
This happens because the class added by the patch is registered in a
subsys_initcall (initcall4), but the pxa pwm driver is registered in
arch_initcall (initcall3). If the class is not registered before the
driver probe function runs, the oops occurs in device_add() when the
uninitialized pointers in struct class are dereferenced. I don't see a
reason that the driver must be an arch_initcall, so this patch makes it
a regular module_platform_driver (initcall6), preventing the oops.

When the transcoder:port mapping on Haswell HDMI/DP audio is changed
during the stream playback, the sound gets lost. Typically this
problem is seen when the user switches the graphics mode from eDP+DP
to DP-only configuration, where CRTC 1 is used for DP in the former
while CRTC 0 is used for the latter.
The graphics controller notifies the change via the normal ELD update
procedure, so we get the intrinsic event. For enabling the sound
again, the HDMI audio driver needs to reset the pin and set up the
audio infoframe again.
This patch achieves it by:
- keep the current status of channels and info frame setup in per_pin
struct,
- check the reconnection in the intrinsic event handler,
- reset the pin and the re-invoke hdmi_setup_audio_infoframe()
accordingly.
The hdmi_setup_audio_infoframe() function has been changed, too, so
that it can be invoked without passing the substream instance.
The patch is mostly based on the work by Mengdong Lin.

Create_CQ verb doesn't provide a PD pointer. So, until now we are
creating all (both userspace and kernel) CQ DB regions from PD0. This
will result in mmapping PD0 to applications. A rogue userspace
application can mess things up.
Also more serious issues is even the be2net NIC uses PD0.
This patch addresses this problem by:
1) Create a PD page for every userspace application when the
alloc_ucontext is called. This will be destroyed in
dealloc_ucontext.
2) All CQs for that context will use the PD allocated in ucontext.
3) The first create_PD call from application will result in returning
the PD address from its ucontext (no new PD will be created).
4) For subsecquent create_pd calls from application, we create new PDs for
the application.
