From: Imre Deak Date: Thu, 1 Nov 2018 14:04:23 +0000 (+0200) Subject: drm/i915: Use a helper to get the aux power domain X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=337837ac3a75f126b53a522bebf2d8b3e82b105b;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Use a helper to get the aux power domain From ICL onwards the AUX power domain may change dynamically based on whether a DDI/TypeC port is in thunderbolt or non-thunderbolt mode, so use a helper function instead of a static field to get the current domain.
