From df66499a1fab340c167250a5743931dc50d5f0fa Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 19 Nov 2019 09:17:05 +0300 Subject: Bluetooth: delete a stray unlock We used to take a lock in amp_physical_cfm() but then we moved it to the caller function. Unfortunately the unlock on this error path was overlooked so it leads to a double unlock.
