Subject: drm/i915: stop using is_pch_edp() in intel_dp_init_connector()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f7d24902e197824eee717e4c3f406eb8623e67e0;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: stop using is_pch_edp() in intel_dp_init_connector()

is_pch_edp() will be removed in a follow-up patch, so replace it
with a check for the port and VBT info (for port-D eDP).

Also make things a bit clearer by using a switch on the ports.

v2:
- make the comment about not setting the conder type for DP clearer
