drm: Add drm_encoder_mask()
Add drm_encoder_mask() which returns the 1<<index for the encoder. We already have an identical drm_crtc_mask() for crtcs. Mostly performed with coccinelle: @@ @@ - (1<<drm_encoder_index( + drm_encoder_mask( ...) - ) @@ @@ - 1<<drm_encoder_index( + drm_encoder_mask( ...) @@ @@ - BIT(drm_encoder_index( + drm_encoder_mask( ...) - ) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180626194716.12522-3-ville.syrjala@linux.intel.com Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
