[Intel-gfx] [PATCH 04/19] drm/i915: Replace is_planar_yuv_format() with drm_format_info_is_yuv_semiplanar()

Mon Jul 8 12:53:10 UTC 2019


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

There's a helper in drm_fourcc.h these days to check of we're dealing
with a two plane YUV format. Make use if it.

Also s/plane/color_plane/ in skl_plane_relative_data_rate() to reduce
the confusion.
