X-Git-Tag: MMI-PSA29.97-13-9~10132^2~2^2~2 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=48afbd70ac7b6aa62e8d452091023941d8085f8a;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git drm/radeon: reset BOs address after clearing it. Otherwise it is possible that we will have page table corruption if we change a BOs address multiple times.
