Conversion to fb_videomode and then comparing with the mixer/hdmi/phy limits is not required. Instead, drm_display_mode fields cane be directly compared. v4: 1) Removed __func__ from DRM_DEBUG_KMS. v3: 1) Replaced check_timing callbacks with check_mode. 2) Change the type of second parameter of check_mode callback from void pointer paramenter to struct drm_display_mode pointer. v2: 1) Removed convert_to_video_timing(). 2) Corrected DRM_DEBUG_KMS to print the resolution properly.
