Move the computation of the interrupt bits to an helper function, and use it everywhere to make sure we always use the right bits. diff 187ad82a Fri Aug 26 13:45:38 MDT 2016 Adrien Destugues <pulkomandy@pulkomandy.tk> intel_extreme: fix wait_for_vblank on SandyBridge There was some mixup with the interrupt registers, still: - The driver uses 16-bit read/write, but on SandyBridge the register is 32 bits - There is a global interrupt enable bit, which must be set to unmask everything else - The bits for vblank interrupt are not the same on SNB and later PCH based devices, and the code mixed the two.
