drm/i915: Drop PIPE-A quirk for 945GSE HP Mini
Since the introduction of BIOS fb preservation, circa 3.17, we began encountering a failure during boot when trying to use force-detect before GEM was initialised. That bug is from commit 7fad798e16fecddd41c6a91728a09f0b9507e40c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jul 4 17:51:47 2012 +0200 drm/i915: ensure the force pipe A quirk is actually followed but investigation of the affected machine revealed that it was using a PIPE-A quirk even though it was a 945GSE and the quirk is only supposed to be used to workaround a hardware issue on 830/845. That quirk was added for this HP Mini in commit 6b93afc564a5e74b0eaaa46c95f557449951b3b9 Author: Bryce Harrington <bryce@bryceharrington.org> Date: Wed May 27 03:40:52 2009 -0700 add pipe a force quirk for Dell mini in order to workaround an issue with the BIOS behaving strangely during lid-close. Since then we have a much larger hammer to thwart the BIOS after opening the lid and the PIPE-A quirk is no longer required.
