drm/i915: Sink rate read should be saved in deca-kHz
The sink rate read from supported link rate table is in KHz as per spec while in drm, the saved clock is in deca-KHz. So divide the link rate by 10 before storing. Reading of rates was added by: commit fc0f8e25318f ("drm/i915/skl: Read sink supported rates from edp panel") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Sonika Jindal <sonika.jindal@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
