drm/amdkfd: Dereference null return value · 23f70373

Andrew Martin authored 4 months ago


In the function pqm_uninit there is a call-assignment of "pdd =
kfd_get_process_device_data" which could be null, and this value was
later dereferenced without checking.

Fixes: fb910658 ("drm/amdkfd: Refactor queue wptr_bo GART mapping")
