Currently, there are many Call Traces when booting kernel on LoongArch,
here are the trimmed kernel log messages:

WARNING: drivers/gpu/drm/amd/amdgpu/amdgpu_irq.c:639 at
amdgpu_irq_put+0xb0/0x140 [amdgpu], CPU#0: kworker/0:0/9
...
Call Trace:
...
The warning can basically only be triggered by two conditions:
1. A fatal problem while loading the driver and the error handling is not 100%
clean.
2. A driver coding error.
And we really need to catch all of those, so there is no real rational to limit
the warning.
I mean when you run into any of those they should potentially be fixed at some
point.
I did the following change and it can fix the problem, given that I am
not familiar with amdgpu driver, could you please check it? If it is OK,
I will send a formal patch later.

Mhm, I need to double check that but that looks like not such a bad idea of
hand.
Please let me know whether the above change is OK, if yes I will send a
patch ASAP before the coming merge window.
Thanks,
