drm/nv50/disp: use correct register to determine DP display bpp

2014-03-07T05:30:00Z

commit a7f1c1e65b68e1e1ab70898528d5977ed68a0a7d upstream. Commit 0a0afd282f ("drm/nv50-/disp: move DP link training to core and train from supervisor") added code that uses the wrong register for computing the display bpp, used for bandwidth calculation. Adjust to use the same register as used by exec_clkcmp and nv50_disp_intr_unk20_2_dp.

2014-03-07T05:30:00Z

commit 7d3428cd4b2ad51af86fdbdf8284ca38fa95e601 upstream. Since commit 0fa9061ae8c ("drm/nouveau/mc: handle irq-related setup ourselves"), drm_device->irq_enabled remained unset. This is needed in order to properly wait for a vblank event in the generic drm code.
