[PATCH][next] drm/xe/guc: Fix inverted logic on snapshot->copy check

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

 



Currently the check to see if snapshot->copy has been allocated is
inverted and ends up dereferencing snapshot->copy when free'ing
objects in the array when it is null or not free'ing the objects
when snapshot->copy is allocated. Fix this by using the correct
non-null pointer check logic.
