From 5a54e7c85b8303b84a9b2fbf978a74d625f85a99 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 13 Jul 2014 20:50:15 +0200 Subject: Bluetooth: Convert L2CAP ident spinlock into a mutex The spinlock protecting the L2CAP ident number can be converted into a mutex since the whole processing is run in a workqueue. So instead of using a spinlock, just use a mutex here.
