[media] vsp1: use __maybe_unused for PM handlers
Building without CONFIG_PM results in a harmless warning from
slightly incorrect #ifdef guards:
drivers/media/platform/vsp1/vsp1_drv.c:525:12: error: 'vsp1_pm_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/platform/vsp1/vsp1_drv.c:516:12: error: 'vsp1_pm_runtime_suspend' defined but not used [-Werror=unused-function]
This removes the existing #ifdef and instead marks all four
PM functions as __maybe_unused.

Tuning a card with Sony ASCOT2E produces the following error:

MAX_WRITE_REGSIZE is defined as 10, buf[MAX_WRITE_REGSIZE + 1] buffer is

The problem is that exactly 10 bytes are written in ascot2e_set_params():

ascot2e_write_regs(priv, 0x06, data, 10);

[media] cec: split the timestamp into an rx and tx timestamp
When transmitting a message and waiting for a reply it would be good
to know the time between when the message was transmitted and when
the reply arrived. With only one timestamp field it was set to when
the reply arrived and the original transmit time was overwritten.
Just taking the timestamp in userspace right before CEC_TRANSMIT is
called is not reliable, since the actual transmit can be delayed if
the CEC bus is busy. Only the driver can fill this in accurately.
So split up the ts field into an rx_ts and a tx_ts. Also move the
status fields to after the 'reply' field: they were placed in a
strange position and make much more sense when grouped with the
other status-related fields.
This patch also makes sure that the timestamp is taken as soon as
possible.

Fix a number of bugs that appeared when support for mediabus formats was
added:
- Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled
for HDMI RGB formats, not for YCbCr formats. Since, as the name
says, this setting is for RGB only. So read the InfoFrame to check
the format.
- the quantization range for the pixelport depends on whether the
mediabus code is RGB or not: if it is RGB, then produce full range
RGB values, otherwise produce limited range YCbCr values.
This means that the op_656_range and alt_data_sat fields of the
platform data are no longer used and these will be removed in a
following patch.
- when setting up a new format the RGB quantization range settings
were never updated. Do so, since this depends on the format.

regards to YCbCr output and quantization range handling:
- if the output is not RGB, then disable the full-to-limited range
CSC matrix since that is meant for RGB formats. YCbCr formats are
always limited range, so there is nothing to convert. (OK, full
range YCbCr is possible, but we don't support that right now).
- the mediabus code that was passed to adv7511_set_fmt was always cleared
by the memset in adv7511_fill_format. This made it effectively impossible
to select YCbCr output.
- adv7511_set_fmt never updated the rgb quantization range.

Fix RC5 decoding with Fintek CIR chipset
Commit
e87b540be2dd02552fb9244d50ae8b4e4619a34b tightened up the RC5
decoding by adding a check for trailing silence to ensure a valid RC5
command had been received. Unfortunately the trailer length checked was
10 units and the Fintek CIR device does not want to provide details of a
space longer than 6350us. This meant that RC5 remotes working on a
Fintek setup on 3.16 failed on 3.17 and later. Fix this by shortening
the trailer check to 6 units (allowing for a previous space in the
received remote command).

[media] zc3xx: Remove deprecated create_singlethread_workqueue
The workqueue "work_thread" is involved in updating parameters for
transfers. It has a single work item(&sd->work) and hence
doesn't require ordering. Also, it is not being used on a memory
reclaim path. Hence, the singlethreaded workqueue has been replaced with
the use of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in sd_stop0() to ensure that there are no
pending tasks while disconnecting the driver.

in the wakeup part.
Also, now that we can set the wakeup sequence via sysfs, there's in
general no need to enable interrupts in the wakeup part.

[media] media: rc: nuvoton: fix rx fifo overrun handling
To detect a rx fifo overrun it's checked whether the number of elements
in the chip fifo exceeds the fifo size. This check can never return true
and is wrong.
Instead we should generate an interrupt if the fifo overruns.
