[PATCH 0/3] drm/ttm: Cleanup state in global ttm structures

From: Brian Yip
Date: Sun Apr 14 2019 - 19:47:09 EST


State in global ttm structures was not properly reset on cleanup.

In the scenario where multiple drm drivers are loaded and the first one
fails to initialize, there is an attempt to reset the global state in
the ttm structures. However, there were some attributes which were not
properly reset during this process. This resulted in a crash and
false positive kobj initialization warnings during subsequent initialization
of these global structures.

Fix the crash and false positive kobj initialization warnings.

Brian Yip (3):
drm/ttm: Reset num_zones on ttm_mem_global cleanup
drm/ttm: Fix ttm_mem_glob.kobj state on cleanup
drm/ttm: Fix ttm_bo_glob.kobj state on cleanup
