摘要:

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

drm/amdgpu/vcn: remove irq disabling in vcn 5 suspend

We do not directly enable/disable VCN IRQ in vcn 5.0.0.
And we do not handle the IRQ state as well. So the calls to
disable IRQ and set state are removed. This effectively gets
rid of the warining of
"WARN_ON(!amdgpu_irq_enabled(adev, src, type))"
in amdgpu_irq_put().
