media: v4l2-fwnode: Fix subdev owner overwritten in v4l2_async_register_subdev_sensor()

2026-06-05T07:28:03+00:00

The v4l2 helper v4l2_async_register_subdev_sensor() calls v4l2_async_register_subdev(), which is a macro that expands to __v4l2_async_register_subdev(sd,THIS_MODULE). Since the macro is expanded inside v4l2-fwnode.c, THIS_MODULE resolves to the v4l2-fwnode module rather than the sensor driver module that originally set sd->owner. When v4l2-fwnode is built-in, THIS_MODULE evaluates to NULL, which then overwrites the sensor driver's owner with NULL. This causes the problem that the sensor module's reference count is never incremented during async registration, so the module can be removed while the subdevice is still in use by a notifier (e.g., a CSI-2 receiver bridge driver). Fix this by renaming v4l2_async_register_subdev_sensor() to __v4l2_async_register_subdev_sensor() with an added explicit module argument and introducing a wrapper macro: #define v4l2_async_register_subdev_sensor(sd) \ __v4l2_async_register_subdev_sensor(sd, THIS_MODULE) This ensures the sensor driver module is properly referenced even when the sensor driver does not init the owner field before calling v4l2_async_register_subdev_sensor() and prevents premature module removal.

media: v4l2-common: add v4l2_fill_pixfmt_mp_aligned helper

2026-05-21T10:32:19+00:00

Add a v4l2_fill_pixfmt_mp_aligned helper which allows the user to specify a custom stride alignment in bytes. This is necessary for hardware like the Rockchip RGA3, which requires the stride value to be aligned to a 16 bytes boundary. The code makes some assumptions about the v4l2 format to simplify the calculation. They currently hold for all known v4l2 formats. v4l2_format_plane_stride uses an unsigned int as argument type to avoid the later multiplication from overflowing the u8 value. All other places use u8, as no practical use cases for a larger alignment are known at the moment.

media: v4l2-common: add has_alpha to v4l2_format_info

2026-05-21T10:32:18+00:00

Add a has_alpha value to the v4l2_format_info struct to indicate if the format contains an alpha component. This information can currently not be queried in a generic way, but might be useful for potential drivers to properly setup alpha blending to copy or set the alpha value. The implementation is based on the drm_format_info implementation. Reviewed-by: Nicolas Dufresne Signed-off-by: Sven Püschel Signed-off-by: Nicolas Dufresne Signed-off-by: Hans Verkuil

media: renesas: vsp1: Split vsp1_du_setup_lif()

2026-05-21T07:10:15+00:00

The vsp1_du_setup_lif() function is used to configure and enable a pipeline, as well as disable it, depending on the cfg argument being a valid pointer or NULL. This creates a confusing API. Improve it by splitting the function in two, a vsp1_du_enable() function to configure a pipeline, and a vsp1_du_disable() function to disaple it. Keep vsp1_du_setup_lif() as an inline wrapper for existing callers in the DRM subsystem, to simplify merging. The callers will be updated separately and the old API will then be removed.

The media_entity_cleanup() function is defined in media-entity.h as a static inline no-op when CONFIG_MEDIA_CONTROLLER is enabled, and as a no-op macro otherwise. This complexity is unneeded. Use a static inline function in all cases.
