Subject: Bluetooth: Use the ERTM transmit state machine from timeout handlers
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=80909e04de4dbbe76a220ccd5f9b32d8d5a8c22c;p=linux-beck.git

Bluetooth: Use the ERTM transmit state machine from timeout handlers

Different states have different actions for retransmit and monitor
timeouts, so remove the logic for those actions from the timer handlers.
