Subject: Bluetooth: Stop ack_timer if ERTM enters in Local Busy or SREJ_SENT
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7fe9b298c98fdfecf3b0efb4c971b7696d091ae9;p=deliverable%2Flinux.git

Bluetooth: Stop ack_timer if ERTM enters in Local Busy or SREJ_SENT

The ack_timer is implemation specific, disabling it in such situation
avoids some potencial errors in the ERTM protocol.
