drm: Inline drm_color_lut_extract()
This thing can get called several thousand times per LUT so seems like we want to inline it to: - avoid the function call overhead - allow constant folding A quick synthetic test (w/o any hardware interaction) with a ridiculously large LUT size shows about 50% reduction in runtime on my HSW and BSW boxes. Slightly less with more reasonable LUT size but still easily measurable in tens of microseconds. v2: Include drm_color_mgmt.h in the .rst (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191108135654.12907-1-ville.syrjala@linux.intel.com
