V4L2_FRAME_DESC_ENTRY_MAX is currently set to 4. In theory it's possible to have an arbitrary amount of streams in a single pad, so preferably there should be no hardcoded maximum number. However, I believe a reasonable max is 8, which would cover a CSI-2 pad with 4 streams of pixel data and 4 streams of metadata. Signed-off-by:

The doc talks about streams and pipelines, but doesn't really define them. This is an attempt to define them according to my understanding. Signed-off-by:

The state argument for the functions for obtaining various parts of the state is NULL if it is called by drivers for active state. Fail graciously in that case instead of dereferencing a NULL pointer. Suggested-by:

What the IMGU driver did was that it first acquired the pointers to active and try V4L2 subdev state, and only then figured out which one to use. The problem with that approach and a later patch (see Fixes: tag) is that as sd_state argument to v4l2_subdev_get_try_crop() et al is NULL, there is now an attempt to dereference that. Fix this. Also rewrap lines a little. Fixes: 0d346d2a ("media: v4l2-subdev: add subdev-wide state struct") Cc: stable@vger.kernel.org # for v5.14 and later Signed-off-by:

The documentation states that the BNR factor is a multiplier coded as u3.13 and with a range of (0, 8). This is not correct, as the isp is adding 1.0 to the gain applied, ie Pout = { Pin * (1 + Gx) }. It means that a gain of 1.0 should be coded as 0.

Commit e33fdb5a ("media: saa7146: deprecate hexium_gemini/orion, mxb and ttpci") moves some media drivers to the staging subsystem, and unfortunately only partially adjusts the entry in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. As the files matching include/media/drv-intf/saa7146* are moved to drivers/staging/media/deprecated/saa7146/common, this directory is already covered by the existing file entry drivers/staging/media/deprecated/saa7146/.

mdp_comp_clock_on will increase runtime PM usage counter, and mdp_comp_clock_off will decrease the runtime PM usage counter. so, if mdp_comp_clock_on failed after increment runtime PM usage counter, it should decrease it before return a error code. pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced. And if failed to enable clk, add pm_runtime_put() to decrease the runtime PM usage counter. Fixes: 61890cca ("media: platform: mtk-mdp3: add MediaTek MDP3 driver") Signed-off-by:
