CVE-2023-53723: drm/amdgpu: disable sdma ecc irq only when sdma RAS is enabled in suspend
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: disable sdma ecc irq only when sdma RAS is enabled in suspend
sdmav40ip is shared on a few asics, but in sdmav40hwfini, driver unconditionally disables eccirq which is only enabled on those asics enabling sdma ecc. This will introduce a warning in suspend cycle on those chips with sdma ip v4.0, while without sdma ecc. So this patch correct this.
