I've found a few issues while I was testing ath10k
in QEMU/KVM with PCI passthrough. The second patch
is something that I've found while analysing the
bmi race and I don't think anyone experienced
problems associated with it.

There's still a weird synchronization issue with
(what I think is) iomap write propagation. The
initial fw bootup interrupt doesn't come in and
it seems CE interrupts are unmasked with a lag
because explicit polling after ctl_resp timeout
seems to be sufficient to work around it. I
suspect this might be a virtualization problem
rather than ath10k. Ideas, anyone?
