[ Upstream commit 8e782fcf78275f505194e767c515202d4fd274bc ]
If userspace has an open file descriptor on the rc input device or lirc
device when rc_unregister_device() is called, then the rc close() is
never called.
This ensures that the receiver is turned off on the nuvoton-cir driver
during shutdown.

[ Upstream commit c764da98a600a4b068d25c77164f092f159cecec ]
The video device release() callback for video-i2c driver frees the whole
struct video_i2c_data. If there is no user left for the video device
when video_unregister_device() is called, the release callback is executed.
However, in video_i2c_remove() some fields (v4l2_dev, lock, and queue_lock)
in struct video_i2c_data are still accessed after video_unregister_device()
is called.
This fixes the use after free by moving the code from video_i2c_remove()
to the release() callback.

of_parse_phandle() returns the device node with refcount incremented.
There are two nodes that are used temporary in mtk_vcodec_init_enc_pm(),
but their refcounts are not decremented.
The patch adds one of_node_put() and fixes returning error codes.

[ Upstream commit 2912289a518077ddb8214e05336700148e97e235 ]
The v4l2_dv_timings_cap struct is used to do sanity checks when setting and
enumerating DV timings, ensuring that only valid timings as per the HW
capabilities are allowed.
However, many drivers just filled in 0 for the minimum width, height or
pixelclock frequency. This can cause timings with e.g. 0 as width and height
to be accepted, which will in turn lead to a potential division by zero.
Fill in proper values are minimum boundaries. 640x350 was chosen since it is
the smallest resolution in v4l2-dv-timings.h. Same for 13 MHz as the lowest
pixelclock frequency (it's slightly below the minimum of 13.5 MHz in the
v4l2-dv-timings.h header).

[ Upstream commit aa35dc3c71950e3fec3e230c06c27c0fbd0067f8 ]
If vpbe_set_default_output() or vpbe_set_default_mode() fails,
vpbe_initialize() returns error code without releasing resources.
The patch adds error handling for that case.
Found by Linux Driver Verification project (linuxtesting.org).

[ Upstream commit 4f9d7225c70dd9d3f406b79e60f8dbd2cd5ae743 ]
The imx274 driver uses regmap and the build will fail without it.
Fixes:
drivers/media/i2c/imx274.c:142:21: error: variable ‘imx274_regmap_config’ has initializer but incomplete type
static const struct regmap_config imx274_regmap_config = {

imx274->regmap = devm_regmap_init_i2c(client, &imx274_regmap_config);
^~~~~~~~~~~~~~~~~~~~

[ Upstream commit 75fa6e4f83a0923fe753827d354998d448b4fd6a ]
Add support for the third loop filter mode
V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY,
and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and
V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls.
The filter offset controls are signed values in the -6 to 6 range and
are stored into the slice header fields slice_alpha_c0_offset_div2 and
slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are
double their value, in range of -12 to 12.
Rename variables to more closely match the nomenclature in the H.264
specification.
