From 8261b19173b89d86cc3088483595e2879e4976d6 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 19 Apr 2011 23:18:09 +0100 Subject: [PATCH] drm/i915: Don't store temporary load-detect variables in the generic encoder Keep all the state required for undoing and restoring the previous pipe configuration together in a single struct passed from intel_get_load_detect_pipe() to intel_release_load_detect_pipe() rather than stuffing them inside the common encoder structure.
