Subject: drm/amd/amdgpu/amdgpu_uvd: Fix forgotten unmap buffer object
Git-commit: db7b81545f5abdfd1f13b7f0a3f995994701cf92
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
After the buffer object is successfully mapped,
call amdgpu_bo_kunmap before the function returns.
