It can be just simple like the patch below. This is rather a tentative workaround. If the hardware (or the corresponding part in the graphics driver) is fixed, we can get rid of it easily. So, just keep the change as small and simple as possible.

Hi Takashi,
I revised the patch as you suggested. Hope we'll have a better solution for Broadwell soon.
Thanks Mengdong
