From 4edd17a25c99f34bd7a75c1daf31afe840237da8 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 3 Aug 2011 10:34:58 -0700 Subject: [PATCH] Revert "drm/i915/dp: Zero the DPCD data before connection probe" This reverts commit 97cdd7101079adc3c626d159c62d43de949516c8. Clearing the dpcd data means that if the fetch fails, any previous data will be lost. On eDP, this is no fun as we only fetch dpcd at init time, so the memset will destroy that the next time through. --- drivers/gpu/drm/i915/intel_dp.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index ba72fbcbbbc9..2f901c05ea2c 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1697,7 +1697,6 @@ intel_dp_detect(struct drm_connector *connector, bool force) struct edid *edid = NULL; intel_dp->has_audio = false; - memset(intel_dp->dpcd, 0, sizeof(intel_dp->dpcd)); if (HAS_PCH_SPLIT(dev)) status = ironlake_dp_detect(intel_dp); -- 2.39.5
