Daniel Vetter a2bd1f541f drm/i915: check whether we actually received an edid in detect_ddc ... Somehow detect_ddc manages to fall through all checks when we think that something responds on the ddc i2c address, but the edid read failed. Fix this up by explicitly checking for this case. This fixes a regression on newer chips because since commit aaa377302b Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Jun 16 15:30:32 2012 +0200 drm/i915/crt: Do not rely upon the HPD presence pin we use ddc detection also on hotplug capable platforms. And one of these reads all 0s for any i2c transaction if nothing is connected to the vga port. v2: Implement Chris Wilson's review: - simplify logic, default to "nothing detected" - kill stale comment - BUG_ON(!crt->type != ANALOG) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=51900 Tested-by: Yang Guang <guang.a.yang@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2012-07-20 12:21:38 +02:00
