6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bokun Zhang <bokun.zhang@xxxxxxx>
[ Upstream commit 3676f37a88432132bcff55a17dc48911239b6d98 ]
- The previous patch only considered the case for baremetal
and is not applicable for SRIOV code path. We also need to
init fw_share for SRIOV VF
Fixes: 928cd772e18f ("drm/amdgpu/vcn: reset fw_shared when VCPU buffers corrupted on vcn v4.0.3")
