Add a mutex to protect resume_force_mode from being called multiple times. This fixes a bug observed on SNB where two wake sources call resume_force_mode and the FDI training fails as a result. The user facing result of this is complete screen corruption.
Looks like a bug in i915_drv.c for calling that function without holding the mode_config.lock
Good catch, thanks for the feedback Chris.
I'll submit a new patch to intel-gfx, please drop this one.
