drm: Add function to convert rect in 16.16 fixed format to regular format
Much more clear to read one function call than four lines doing this conversion. v7: - function renamed - calculating width and height before truncate - inlined v10: - renamed parameters from source and destination to src and dst to match sister functions Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: dri-devel@lists.freedesktop.org Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Reviewed-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210104205654.238928-1-jose.souza@intel.com
