PTR_ERR(NULL) which is success.

[media] s5p-cec: mark PM functions as __maybe_unused again
A bugfix removed the two callers of s5p_cec_runtime_suspend

[media] videodev2.h Add HSV formats
These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
useful format for image segmentation algorithms.
