Description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: disable sdma ecc irq only when sdma RAS is enabled in suspend sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini, driver unconditionally disables ecc_irq 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.
