Christophe JAILLET f81a18d860 [media] tm6000: Fix resource freeing in 'tm6000_prepare_isoc()'
'usb_free_urb(urb)' is a no-op, because urb is known to be NULL.

It is likelly that releasing resources allocated by
'tm6000_alloc_urb_buffers()' just a few lines above is expected here.

This has been spotted by the following coccinelle script:
@@
expression ret, x, e;
identifier f;
@@

*   if (x == NULL)
    {
     ... when != x = e;
(
*    f(<+...x...+>);
|
*    ret = f(<+...x...+>);
)
     ...

Javier Martinez Canillas c0746c1ad3 [media] tc358743: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Javier Martinez Canillas 9ae05fd1e7 [media] et8ek8: Export OF device ID as module aliases
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.

Before this patch:

$ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias
alias:          i2c:et8ek8

After this patch:

$ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias
alias:          i2c:et8ek8
alias:          of:N*T*Ctoshiba,et8ek8C*

the parameter of this function to which the object references are passed
is of type const. So, stv0299_config structures having this property

Based on an earlier version from Russell King:

https://patchwork.kernel.org/patch/9277043/

The cec_notifier is a reference counted object containing the CEC physical address
state of a video device.

When a new notifier is registered the current state will be reported to
that notifier at registration time.

Kieran Bingham 4461c84b52 [media] v4l: vsp1: Prevent multiple streamon race commencing pipeline early
With multiple inputs through the BRU it is feasible for the streams to
race each other at stream-on.

Multiple VIDIOC_STREAMON calls racing each other could have process
N-1 skipping over the pipeline setup section and then start the pipeline
early, if videobuf2 has already enqueued buffers to the driver for
process N but not called the .start_streaming() operation yet

In the case of the video pipelines, this
can present two serious issues.

 1) A null-dereference if the pipe->dl is committed at the same time as
    the vsp1_video_setup_pipeline() is processing

 2) A hardware hang, where a display list is committed without having
    called vsp1_video_setup_pipeline() first

Repair this issue, by ensuring that only the stream which configures the
pipeline is able to start it.

Hans Verkuil ba7ed691dc [media] v4l2-compat-ioctl32: VIDIOC_S_EDID should return all fields on error
Most ioctls do not have to write back the contents of the argument
if an error is returned. But VIDIOC_S_EDID is an exception together
with the EXT_CTRLS ioctls (already handled correctly).

Add this exception to v4l2-compat-ioctl32.

This fixes a compliance error when using compat32 and trying to
set a new EDID with more blocks than the hardware supports. In
that case the driver will return -E2BIG and set edid.blocks to the
actual maximum number of blocks. This field was never copied back
to userspace due to this bug.

Arnd Bergmann 51d979c0bb [media] vcodec: mediatek: mark pm functions as __maybe_unused
When CONFIG_PM is disabled, we get a couple of unused functions:

drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:927:13: error: 'mtk_jpeg_clk_off' defined but not used [-Werror=unused-function]
 static void mtk_jpeg_clk_off(struct mtk_jpeg_dev *jpeg)
             ^~~~~~~~~~~~~~~~
drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:916:13: error: 'mtk_jpeg_clk_on' defined but not used [-Werror=unused-function]
 static void mtk_jpeg_clk_on(struct mtk_jpeg_dev *jpeg)

Rather than adding more error-prone #ifdefs around those, this patch
removes the existing #ifdef checks and marks the PM functions as __maybe_unused
to let gcc do the right thing.

Marek Szyprowski d251510d4c [media] s5p-mfc: Don't allocate codec buffers from pre-allocated region
Further investigation revealed that codec buffers also don't need to
be allocated at higher addresses than firmware base for MFC v6+ hardware.
Those buffers can be quite large and its size depends on the selected
format and framesize. This patch changes the way the codec buffers are
allocated - driver will use generic allocator for them instead of the
pre-allocated buffer for firmware and contexts.
