From 86aae6c7b577654b7293374973985a153e0c147e Mon Sep 17 00:00:00 2001 From: Libor Pechacek Date: Tue, 29 Apr 2014 20:38:34 +0200 Subject: Bluetooth: Convert RFCOMM spinlocks into mutexes Enabling CONFIG_DEBUG_ATOMIC_SLEEP has shown that some rfcomm functions acquiring spinlocks call sleeping locks further in the chain. Converting the offending spinlocks into mutexes makes sleeping safe.
