| Subject: drm/amdkfd: destroy dbgmgr in notifier release |
| |
| From: Oded Gabbay <oded.gabbay@gmail.com> |
| |
| commit bc4755a4bd1845ef6e88ac8c62f12e05bb530256 upstream. |
| |
| amdkfd need to destroy the debug manager in case amdkfd's notifier |
| function is called before the unbind function, because in that case, |
| the unbind function will exit without destroying debug manager. |
