The only way to untaint a kernel is a reboot. A taint just means "something
happened to this kernel since it was booted". It's used as a hint, and
that's all.

I agree with the other comments in this thread. Use devlink health or
whatever tool to look further into causes. But from what I see here, this
code is "good enough" for a taint.
