Subject: drm/i915: Rename i915_dp_detect_common to intel_dp_get_dpcd
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=26d61aad7a46115628341e9eb95433f30efef21a;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: Rename i915_dp_detect_common to intel_dp_get_dpcd

This describes the function better, allowing it to be used where the
DPCD value is relevant.
