[Intel-gfx] [PATCH 44/66] drm/i915: Pass port explicitly to intel_ddi_get_hw_state

[Daniel Vetter]

Well, the newly created intel_ddi_get_port_state.

In general intel_ddi.c has way too intimate knowledge with everyone
else as exemplified with all the encoder/connector noodling and the
massive exported function list.

As a first step explictly pass around the port, first in the encoder
callback.
