Hi

From: Ville Syrjälä ville.syrjala@linux.intel.com
drm_mode_equal_no_clocks() is like drm_mode_equal() except it doesn't compare the clock or vrefresh values. drm_mode_equal() is now implemented by first doing the clock checks, and then calling drm_mode_equal_no_clocks().

EXPORT_SYMBOL(drm_mode_equal) is gone. I'd also add a newline here.
