From b17e73bb4269f47e1ea2d64a834f1cfc8644fabb Mon Sep 17 00:00:00 2001 From: Szymon Janc Date: Wed, 11 Jan 2012 10:59:47 +0100 Subject: [PATCH] Bluetooth: Clear ack_timer when sending ack ack_timer should be cleared when sending ACK to avoid acking I-frames twice. This commit introduces helper function (only send ack, not clearing timer) which is used by l2cap_send_ack and l2cap_ack_timeout. This is to avoid clearing ack timer in timer function.
