From ab4d966c522f84b385d87f5ed2b622a7e4c22a6b Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Wed, 31 Oct 2012 18:12:55 -0200 Subject: [PATCH] drm/i915: don't assert disabled FDI before disabling the FDI On Haswell/LPT we must disable the PCH transcoder before we disable the FDI, so don't check for disabled FDI there.
