When Stopping lightdm and removing amdgpu driver are executed, the following
error is triggered probably:
Unable to handle kernel paging request at virtual address 0000000000005e00

The adev->rmmio has been unmmaped in amdgpu_device_fini_hw().
So skip disabling audio when device is unplugged.

Good catch, but that looks like a workaround for something done in the wrong place.
A *_sw_fini() function should not enable/disable HW.

Should we move audio disabling to hw_fini()?

Yes and when you look at the patch Alex pointed out that is pretty much exactly what it does.
So still good catch from your side, but a fix is already in the pipeline.
