Subject[PATCH][next] drm/amdgpu: fix uninitialized variable pasid_mapping_needed
Date
From: Colin Ian King <colin.king@canonical.com>

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")
