Subject: [PATCH v2 3/3] drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v10_0_hw_fini
The gmc.ecc_irq is enabled by firmware per IFWI setting,
and the host driver is not privileged to enable/disable
the interrupt. So, it is meaningless to use the amdgpu_irq_put
function in gmc_v10_0_hw_fini, which also leads to the call
trace.
