Subject: [PATCH] drm: Use C8 instead of RGB332 when determining the format
 from depth/bpp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit d84f031bd230fdf9c3b7734940c859bf28b90219 upstream.

Support for real RGB332 is a rarity, most hardware only really support
C8. So use C8 instead of RGB332 when determining the format based on
depth/bpp.

This fixes 8bpp fbcon on i915, since i915 will only accept C8 and not
RGB332.
