From 7bc18d9d3d7ffbc09dabb201933a063583a39027 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 16 Oct 2013 18:11:39 +0300 Subject: [PATCH] Bluetooth: Convert auto accept timer to use delayed work Since the entire Bluetooth subsystem runs in workqueues these days there is no need to use a timer for deferring work.
