Subject: [PATCH 4033/4256] drm/amdgpu: fix uninitialized variable
pasid_mapping_needed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The boolean variable pasid_mapping_needed is not initialized and
there are code paths that do not assign it any value before it is
is read later. Fix this by initializing pasid_mapping_needed to
false.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 6817bf283b2b ("drm/amdgpu: grab the id mgr lock while accessing passid_mapping")
