There is often a need to print the name of a pixel format. Printing the raw numeric value is hard to decipher, printing the four ASCII characters is slightly more human-friendly but still needs a decoder table. Add a name that can be printed easily. The bulk of this patch was done with: sed -i -e 's/\.format = DRM_FORMAT_\(.\+\),/DRM_FORMAT(\1),/' libweston/pixel-formats.c Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
