16844fb1e6
This patch renames check_timing to check_mode and removes the unnecessary conversion of drm_display_mode to/from fb_videomode in the hdmi driver. v4: 1) Changed the commit message to add information related to renaming the callbacks to check_mode. 2) Changed debug message to print 1/0 for interlace mode. 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.
