Hello,

I read this point in staging/wfx/TODO file

- In wfx_cmd_send(), "async" allow to send command without waiting the reply.
It may help in some situation, but it is not yet used. In add, it may cause
some trouble:
https://lore.kernel.org/driverdev-devel/alpine.DEB.2.21.1910041317381.2992@hadrien/
So, fix it (by replacing the mutex with a semaphore) or drop it.

I think that this issue has already been fixed in hif_shutdown() function, hasn't it ?

I have another question. How can (replacing the mutex with a semaphore) solve the problem?

Thank You.
