[PATCH 1/2] drm/i915: Clean up the mess around hdmi_12bpc_possible()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Move the crtc state related 12bpc checks into hdmi_12bpc_possible()
since that one already examines other parts of the crtc state.

Note that we can drop the !force_dvi check since
crtc_state->has_hdmi_sink already accounts for that.
