Subject: [PATCH 0/2] Reduce delay after sending baudrate request for WCN3990

The current 300ms delay after a baudrate change is extremely long.
For WCM3990 it is sufficient to wait 10ms after the baudrate change
request has been sent over the wire.

Also use msleep() instead of a set_current_state() / schedule_timeout()
combo.

Matthias Kaehlcke (2):
  hci_qca: Use msleep() instead of open coding it
  hci_qca: Reduce delay after sending baudrate request for WCN3990
