If we're using vga switcheroo, the device may be turned off and poking at it can cause an oops.
I added just a couple more details to the changelog and added to my -fixes queue.
The question for the audience is: what is the difference between using the PCI power state and the drm->power_switch_state?
Seems possible we could use either. I picked the latter because i915_switcheroo_set_state() seems to be keeping it in sync with power state and has the "changing" state, which might help reduce races. Thanks,
