From 5bc40472dea771260dc6d6946fd09c1ac3c9cd93 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 19 Jan 2016 11:35:53 -0200 Subject: [PATCH] drm/i915/fbc: don't try to deactivate FBC if it's not enabled During FBC invalidation, don't call intel_fbc_deactivate if it's not enabled. This doesn't fix any bug, but helps making the interface saner.
