[PATCH 4/5] drm/i915: clear opregon->lid_state after we unmap it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx>

We don't seem to be using the pointer after it's unmapped, so this
patch doesn't fix any bug I can reproduce.
