We got the following warning when booting the kernel:
[ 3.243674] INFO: trying to register non-static key.

The lock 'vc->qlock' will be initialized in tw686x_video_init(), but the

A pointer into virtual memory is represented by a (void *)
not an u32, so the compiler warns:

When SCP timeout during playing video, kernel crashes with following
message. It's caused by accessing NULL pointer in vpu_dec_ipi_handler.
This patch doesn't solve the root cause of NULL pointer, but merely
prevent kernel crashed when encounter the NULL pointer.
After applied this patch, kernel keeps alive, only the video player turns
to green screen.

This is a very old driver for very old hardware and it is one of
the very few remaining that does not use the vb2 framework (or
even the older videobuf framework), so deprecate this driver
and move it to staging with the intent to removing it altogether
by the end of 2022.
If someone wants to keep this driver, then it has to be converted

This inserts 4 pixels of the RGB color 0xab55ab at the left hand side of
the image. This is only done for 3 or 4 byte RGB pixel formats. The HDMI
TMDS encoding of this pixel value equals the Video Guard Band value as
defined by HDMI (see section 5.2.2.1 in the HDMI 1.3 Specification) that
preceeds the first actual pixel of a video line. If an HDMI receiver
doesn't handle this correctly, then it might keep skipping these Video
Guard Band patterns and end up with a shorter video line. So this is a
nice pattern to test with.

To simplify the driver's maintenance it makes sense to escape from
hardcoded numbers of power domain resources per platform and statical
allocation of the resources. For instance on a QCOM SM8450 platform
the number of CAMSS power domains shall be bumped up to 6, also notably
CAMSS on MSM8916 has only one power domain, however it expects to get 2,
and thus it should result in a runtime error on driver probe.
The change fixes an issue mentioned above and gives more flexibility
to support more platforms in future.
