For smu v13_0_2, if the GPU supports xgmi, refer to

commit f5c7e7797060 ("drm/amdgpu: Adjust removal control flow for smu v13_0_2"),

it will run gpu recover in AMDGPU_RESET_FOR_DEVICE_REMOVE mode when removing,

which makes all devices in hive list have hw reset but no resume except the

basic ip blocks, then other ip blocks will not call .hw_fini according to

ip_block.status.hw.

Since psp_free_shared_bufs just includes some software operations, so move

it to psp_sw_fini.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
