Description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx ras

gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert. So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq should be executed under such condition, otherwise, an amdgpu_irq_put calltrace will occur.
