Subject: drm/i915: Print pretty names for pixel formats
X-Git-Tag: accepted/tizen/20130625.160735~2^2^2~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4ee62c7669be1a6f1dd407e5ba7e38c0e2204e92;p=profile%2Fivi%2Fkernel-x86-ivi.git

drm/i915: Print pretty names for pixel formats

Use drm_get_format_name to print more readable pixel format names
in debug output.

Also unify the debug messages to say "unsupported pixel format",
which better describes what is going on.
