I don't know if it was necessary (or at least helped in the power-off
case) without this series, but my testing suggests it is not needed
with the delay after the power off pulse ("[3/3] Bluetooth: hci_qca:
Add delay after power-off pulse").

I'll send a new version without the delay.

Thanks

Matthias
