[Intel-gfx] [PATCH] Fix list empty check in i915_gem_evict_everything

[Zhiyuan Lv]

That seems to be a typo. The original code will override the previous
list empty check value in the loop. As the result, only the last vm in
vm_list impacts the empty check. The problem is fixed by using local
bool variable inside the loop.
