[Intel-gfx] [PATCH v2 09/11] drm/i915: Turn intel_digital_port_connected() in a vfunc

Tue Jan 21 19:44:03 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Let's get rid of the platform if ladders in
intel_digital_port_connected() and make it a vfunc. Now the if
ladders are at the encoder initialization which makes them a bit
less convoluted.
v2: Add forward decl for intel_encoder in intel_tc.h
