    drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v11_0_hw_fini · 13af5561
    Horatio Zhang authored
    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_v11_0_hw_fini, which also leads to the call
    trace.
