Description

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