Hmm, I get your point, but whatever the reason why, it should still not make
any null pointer de-reference.

However, did you see that this is for the i965G platform, which is 10 years
old? Is the non-generic driver supporting this platform?

Well, I already wrote a patch that papers around the issue and will still
report it in the logs[1], but this is not a proper patch.

I do not have any background in the sound subsystem, so I do not know what are
the correct assumptions to have, especially around the binding and unbinding of
the driver. I am merely doing some QA/CI job here, and reporting the issue to
you, who own this code.

I am however willing to help, but not by configuring the system differently in
order to get rid of the problem. This would be a workaround, not a fix.
