[The upstream commit above is a combination of revert + one-liner fix. This patch contains only the latter that is needed for 2.6.37.x.] This patch fixes the backlight level calculation for combination mode used in some models like GM45. It's due to a wrong bit shift introduced by the commit a95735569312f2ab0c80425e2cd1e5cb0b4e1870 drm/i915: Refactor panel backlight controls Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=23472 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=34524 Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=672946 Signed-off-by: Takashi Iwai --- Reading git-diff-tree failed
