media: imx: Constify static struct v4l2_m2m_ops The only usage of m2m_ops is to pass its address to v4l2_m2m_init(), which takes a pointer to const v4l2_m2m_ops as argument. Make it const to allow the compiler to put it in read-only memory.

media: imx: Fix csc/scaler unregister The csc/scaler device private struct is released by ipu_csc_scaler_video_device_release(), which can be called by video_unregister_device() if there are no users of the underlying struct video device. Therefore, the mutex can't be held when calling video_unregister_device() as its memory may be freed by it, leading to a kernel oops. Fortunately, the fix is quite simple as no locking is needed when calling video_unregister_device(): v4l2-core already has its own internal locking, and the structures are also properly refcounted.

media: imx: utils: Rename format lookup and enumeration functions Rename the format lookup and enumeration functions according to their usage: - Rename imx_media_(find|enum)_format() to *_pixel_format() to explicitly state on what formats the functions operate. This aligns the naming scheme with the media bus and IPU format functions that already end with *_mbus_format() and *_ipu_formats(). - Rename all enumeration functions to pluralize 'formats' at the end, as they enumerate multiple formats.

media: imx: utils: Rename pixel format selection enumeration After the introduction of the CS_SEL_BAYER flag, the "codespace" pixel format selection enumeration wording no longer makes sense (and even before, when selecting between YUV or RGB formats, "codespace" was a misuse of the term). Rename - 'enum codespace_sel' to 'enum imx_pixfmt_sel' - CS_SEL_* to PIXFMT_SEL_* - local vars named cs_sel to fmt_sel or just sel No functional changes.

media: imx: utils: Handle Bayer format lookup through a selection flag The format lookup (and enumeration) functions take a boolean flag to tell if Bayer formats should be considered. This leads to hard to read lines such as return enum_format(fourcc, NULL, index, cs_sel, true, false); where the boolean parameters can easily be mixed. To make the code clearer, add a CS_SEL_BAYER flag that can be passed through the codespace_sel parameter of the lookup functions to replace the bool parameter. [slongerbeam@gmail.com: Instead of declaring CS_SEL_ANY as a bitfield containing only CS_SEL_YUV | CS_SEL_RGB, declare CS_SEL_ANY as all of the above (YUV, RGB, BAYER). A new enum is declared for the YUV | RGB selection as CS_SEL_YUV_RGB, and that is used by sub-devices that don't support BAYER and only allow selecting and enumerating YUV or RGB encodings. CS_SEL_ANY is now only used by the CSI sub-devices and the attached capture interfaces, since only those devices support BAYER formats.] Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
