| |
2.6.35-stable review patch. If anyone has any objections, please let us know.
------------------
From: Chris Wilson <chris@chris-wilson.co.uk>
commit 12e8ba25ef52f19e7a42e61aecb3c1fef83b2a82 upstream.
This reverts commit 0f3ee801b332d6ff22285386675fe5aaedf035c3.
Enabling LVDS on pipe A was causing excessive wakeups on otherwise idle systems due to i915 interrupts. So restrict the LVDS to pipe B once more, whilst the issue is properly diagnosed.
