Change in v3: - Fix build error in kms_color.c:the previous patch mistakenly changed primary->crtc to primary->pipe, which caused compilation to fail. Change in v2: - Replace the depth_10bit variable with is_mtk to simplify the logic. - Include a code comment to clarify the justification for using 0xFFD0 as the maximum threshold for the Gamma LUT.
