From: Michel Dänzer <michel.daenzer@xxxxxxx> Otherwise this can also prevent modesets e.g. for switching VTs, when multiple monitors with different native resolutions are connected. The depths must match though, so keep the != test for that. Also update the DRM_DEBUG output to be slightly more accurate, this doesn't only affect requests from userspace.
