media: v4l: Add definitions for HEVC stateless decoding
This introduces the required definitions for HEVC decoding support with
stateless VPUs. The controls associated to the HEVC slice format provide
the required meta-data for decoding slices extracted from the bitstream.
They are not exported to the public V4L2 API since reworking this API
will likely be needed for covering various use-cases and new hardware.
Multi-slice decoding is exposed as a valid decoding mode to match current
H.264 support but it is not yet implemented.
The interface comes with the following limitations:
* No custom quantization matrices (scaling lists);
* Support for a single temporal layer only;
* No slice entry point offsets support;
* No conformance window support;
* No VUI parameters support;
* No support for SPS extensions: range, multilayer, 3d, scc, 4 bits;
* No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

media: imx: Move pads init to probe
If a subdevice is unregistered and then registered again without the
driver being removed and re-probed (which will happen when the media
device is removed and re-probed without also removing/re-probing the
subdevice), media_device_register_entity() is called with a non-zero
entity->num_pads, and then the subdevice's .registered callback calls
media_entity_pads_init(). Thus the subdevice's pad objects are added
to the media device pad list twice, causing list corruption.
One way to fix this would be to create media_entity_pads_destroy(),
and call it in the subdevice's .unregistered callback. But calling
media_entity_pads_init() in the .registered callbacks was done for
legacy reasons and is no longer necessary, so move the call to
media_entity_pads_init() into the subdevice's probe functions. This
fixes the duplicate pad obejcts in the media device pad list.

media: imx: Move capture device init to registered
If the CSI is unregistered and then registered again without the
driver being removed and re-probed (which will happen when the media
device is removed and re-probed without also removing/re-probing the
CSI), the result is the kobject error and backtrace "tried to init an
initialized object". This is because the video device is left in an
initialized state after being unregistered, thus the video device's
underlying kobject is also left in an initialized state when the device
is registered again.
Fix this by moving imx_media_capture_device_init() and _remove()
into csi_registered() and csi_unregistered(). This will create a new
un-initialized video device when the CSI is re-registered. Do this for
all the subdevices that register a capture device.

media: usbvision: Fix races among open, close, and disconnect
Visual inspection of the usbvision driver shows that it suffers from
three races between its open, close, and disconnect handlers. In
particular, the driver is careful to update its usbvision->user and
usbvision->remove_pending flags while holding the private mutex, but:
usbvision_v4l2_close() and usbvision_radio_close() don't hold
the mutex while they check the value of
usbvision->remove_pending;
usbvision_disconnect() doesn't hold the mutex while checking
the value of usbvision->user; and
also, usbvision_v4l2_open() and usbvision_radio_open() don't
check whether the device has been unplugged before allowing
the user to open the device files.
Each of these can potentially lead to usbvision_release() being called
twice and use-after-free errors.
This patch fixes the races by reading the flags while the mutex is
still held and checking for pending removes before allowing an open to
succeed.

media: usbvision: Fix invalid accesses after device disconnect
The syzbot fuzzer found two invalid-access bugs in the usbvision
driver. These bugs occur when userspace keeps the device file open
after the device has been disconnected and usbvision_disconnect() has
set usbvision->dev to NULL:
When the device file is closed, usbvision_radio_close() tries
to issue a usb_set_interface() call, passing the NULL pointer
as its first argument.
If userspace performs a querycap ioctl call, vidioc_querycap()
calls usb_make_path() with the same NULL pointer.
This patch fixes the problems by making the appropriate tests
beforehand. Note that vidioc_querycap() is protected by
usbvision->v4l2_lock, acquired in a higher layer of the V4L2
subsystem.
