BTW. I applied anyway because suspend/resume was already broken (you
spotted that we don't clear the suspended flag for example).

Fixing the flag alone helps a bit. We can't use the modem if we
suspend/resume with the open port, but closing and re-opening works.

Lockdep also picked-up a A->B B->A between the port mutex and the pmz
irq mutex on suspend.

I'll try to fix all these, and will let you know (I may not have time
today).

Cheers,
Ben.
