From 7be9a2f8c5179520a7d5570e648e0c97d09e4fae Mon Sep 17 00:00:00 2001 From: Horatio Zhang Date: Fri, 24 Feb 2023 13:55:44 +0800 Subject: [PATCH] drm/amdgpu: fix ttm_bo calltrace warning in psp_hw_fini [ Upstream commit 23f4a2d29ba57bf88095f817de5809d427fcbe7e ] The call trace occurs when the amdgpu is removed after the mode1 reset. During mode1 reset, from suspend to resume, there is no need to reinitialize the ta firmware buffer which caused the bo pin_count increase redundantly.
