4c6e097629 media: uvcvideo: Fix pixel format change for Elgato Cam Link 4K
The Elgato Cam Link 4K HDMI video capture card reports to support three
different pixel formats, where the first format depends on the connected
HDMI device.

```
$ v4l2-ctl -d /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
	Type: Video Capture

	[0]: 'NV12' (Y/CbCr 4:2:0)
		Size: Discrete 3840x2160
			Interval: Discrete 0.033s (29.970 fps)
	[1]: 'NV12' (Y/CbCr 4:2:0)
		Size: Discrete 3840x2160
			Interval: Discrete 0.033s (29.970 fps)
	[2]: 'YU12' (Planar YUV 4:2:0)
		Size: Discrete 3840x2160
			Interval: Discrete 0.033s (29.970 fps)
```

Changing the pixel format to anything besides the first pixel format
does not work:

```
$ v4l2-ctl -d /dev/video0 --try-fmt-video pixelformat=YU12
Format Video Capture:
	Width/Height      : 3840/2160
	Pixel Format      : 'NV12' (Y/CbCr 4:2:0)
	Field             : None
	Bytes per Line    : 3840
	Size Image        : 12441600
	Colorspace        : sRGB
	Transfer Function : Rec. 709
	YCbCr/HSV Encoding: Rec. 709
	Quantization      : Default (maps to Limited Range)
	Flags             :
```

User space applications like VLC might show an error message on the
terminal in that case:

```
libv4l2: error set_fmt gave us a different result than try_fmt!
```

Depending on the error handling of the user space applications, they
might display a distorted video, because they use the wrong pixel format
for decoding the stream.

The Elgato Cam Link 4K responds to the USB video probe
VS_PROBE_CONTROL/VS_COMMIT_CONTROL with a malformed data structure: The
second byte contains bFormatIndex (instead of being the second byte of
bmHint). The first byte is always zero. The third byte is always 1.

The firmware bug was reported to Elgato on 2020-12-01 and it was
forwarded by the support team to the developers as feature request.
There is no firmware update available since then. The latest firmware
for Elgato Cam Link 4K as of 2021-03-23 has MCU 20.02.19 and FPGA 67.

Therefore correct the malformed data structure for this device. The
change was successfully tested with VLC, OBS, and Chromium using
different pixel formats (YUYV, NV12, YU12), resolutions (3840x2160,
1920x1080), and frame rates (29.970 and 59.940 fps).

3d42c93e5f media: dmxdev: change the check for problems allocing secfeed
While the logic there is right, it tricks static check analyzers,
like smatch:

	drivers/media/dvb-core/dmxdev.c:729 dvb_dmxdev_filter_start() error: we previously assumed '*secfeed' could be null (see line 719)

Because the implementation of the filter itself is made via
a callback, with its real implementation at the
dvbdmx_allocate_section_feed() inside dvb_demux.c.

So, change the check logic to make it clear that the function
will not try to use *secfeed == NULL.

Implement all the logic to get G2 hardware decoding HEVC frames.
It supports up level 5.1 HEVC stream.
It doesn't support yet 10 bits formats or the scaling feature.

Add HANTRO HEVC dedicated control to skip some bits at the beginning
of the slice header. That is very specific to this hardware so can't
go into uapi structures. Computing the needed value is complex and requires
information from the stream that only the userland knows so let it
provide the correct value to the driver.

9ad1efee08 media: dvd_usb: memory leak in cinergyt2_fe_attach
When the driver fails to talk with the hardware with dvb_usb_generic_rw,
it will return an error to dvb_usb_adapter_frontend_init. However, the
driver forgets to free the resource (e.g., struct cinergyt2_fe_state),
which leads to a memory leak.

Fix this by freeing struct cinergyt2_fe_state when dvb_usb_generic_rw
fails in cinergyt2_frontend_attach.

5507b10109 media: atmel: atmel-isc: extend pipeline with extra modules
Newer ISC pipelines have the additional modules of
Defective Pixel Correction -> DPC itself,
Defective Pixel Correction -> Green Disparity Correction (DPC_GDC)
Defective Pixel Correction -> Black Level Correction (DPC_BLC)
Vertical and Horizontal Scaler -> VHXS

Some products have this full pipeline (sama7g5), other products do not (sama5d2)

Add the modules to the isc base, and also extend the register range to include
the modules.

e891009857 media: atmel: atmel-isc: add DMA to register offsets
The DMA submodule is a part of the atmel-isc pipeline, and stands for
Direct Memory Access. It acts like a master on the AXI bus of the SoC, and
can directly write the RAM area with the pixel data from the ISC internal
sram.
Add dma to the reg offsets struct.
This will allow different products to have a different reg offset for this
particular module.

The RLP submodule is a part of the atmel-isc pipeline, and stands for
Rounding,Limiting and Packaging. It used to extract specific data from the
ISC pipeline. For example if we want to output greyscale 8 bit, we would
use limiting to 8 bits, and packaging to Luma component only.
Add rlp to the reg offsets struct.
This will allow different products to have a different reg offset for this
particular module.

The SUB submodules are a part of the atmel-isc pipeline, and stand for
Subsampling. They are used to subsample the original YUV 4:4:4 pixel ratio
aspect to either 4:2:2 or 4:2:0.
Add sub420 and sub422 to the reg offsets struct.
This will allow different products to have a different reg offset for these

The CBC submodule is a part of the atmel-isc pipeline, and stands for

luma (Y) and chroma (U, V) components of the YUV elements.
The CBC submodule should be initialized in the product specific driver
as it's product specific. Other products can implement it differently
