enable bus mastering on i915 at resume time
On 9xx chips, bus mastering needs to be enabled at resume time for much of the chip to function. With this patch, vblank interrupts will work as expected on resume, along with other chip functions. Fixes kernel bugzilla #10844. Signed-off-by: Jie Luo <clotho67@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
