staging: media: max96712: drop unneeded dependency on OF_GPIO

2026-06-08T08:37:09+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs and are private to GPIOLIB anyway so there's
really no reason to select it explicitly.

media: staging: imx: remove unnecessary out-of-memory error message

2026-05-27T08:58:27+00:00

Remove dev_err() call after dma_alloc_coherent() failure.

checkpatch.pl reports this as an unnecessary out-of-memory message because
failure is already conveyed by returning -ENOMEM, and the current message
does not provide additional useful debugging information.

media: staging: imx-csi: use media_pad_is_streaming helper

2026-05-27T08:58:27+00:00

The media_pad_is_streaming() helper is explicitly intended to check whether
a pad has been started with media_pipeline_start(). Use it instead of
relying on the implicit assumption that a pad with a pipeline is streaming.

media: staging: imx-csi: explicitly start media pipeline on pad 0

2026-05-27T08:58:27+00:00

entity->pads is an array that contains all the pads of an entity.

Calling __media_pipeline_start() or __media_pipeline_stop() on the pads,
implicitly starts the pipeline with the first pad in this array as origin.

Explicitly use the first pad to start the pipeline to make this more
obvious to the reader.

media: staging: imx-csi: move media_pipeline to video device

2026-05-27T08:58:27+00:00

The imx-media driver has a single imx_media_device. Attaching the
media_pipeline to the imx_media_device prevents the execution of multiple
media pipelines on the device. This should be possible as long as the
media_pipelines don't use the same pads or pads that be configured while
the other media pipeline is streaming.

Move the media_pipeline to the imx_media_video_dev to be able to construct
media pipelines per imx capture device.

If different media pipelines in the media device conflict, the validation
will fail. Thus, the pipeline will fail to start and signal an error to
user space.

media: meson: vdec: Fix memory leak in error path of vdec_open

2026-05-21T10:32:22+00:00

The vdec_open() function previously jumped directly to
err_m2m_release when vdec_init_ctrls() failed, skipping
release of the m2m context. This caused a resource leak.

Fix it by introducing a proper err_m2m_ctx_release label
that calls v4l2_m2m_ctx_release(sess->m2m_ctx) before
releasing the m2m device.

This was identified via kmemleak:

media: cedrus: clean up media device on probe failure

2026-05-21T10:32:21+00:00

cedrus_probe() initializes the media device before registering the video
device, the media controller, and the media device. If any of those later
steps fails, probe returns without calling media_device_cleanup(), so the
media device internals initialized by media_device_init() are left behind.

Add a media-device cleanup label to the probe unwind path and route video
registration failures through it as well.
