From: Geert Uytterhoeven Date: Fri, 8 Jul 2022 18:20:47 +0000 (+0200) Subject: drm/fourcc: Add drm_format_info.is_color_indexed flag X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dc1dc76bd9a48c6aba3efae5eadb9a884043966e;p=linux.git drm/fourcc: Add drm_format_info.is_color_indexed flag Add a flag to struct drm_format_info to indicate if a format is color-indexed, similar to the existing .is_yuv flag. This way generic code and drivers can just check this flag, instead of checking against a list of fourcc formats.
