From 23c453a4af187e06d3d16649f1f3f2d16c132f83 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 15 Oct 2013 21:06:51 +0300 Subject: [PATCH] drm: Pretty print pixel format in drm_fb_get_bpp_depth() and format_check() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit drm_fb_get_bpp_depth() likes to complain about unsupported pixel formats but doesn't bother telling us what the format was. Also format_check() just returns an error when it encouters an invalid format, leaving the user scratching his head trying to figure out why addfb failed. Make life a bit easier by using drm_get_format_name() in both places.
