Subject[PATCH 4.14 53/74] Bluetooth: delete a stray unlock
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

commit df66499a1fab340c167250a5743931dc50d5f0fa upstream.

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.

Fixes: a514b17fab51 ("Bluetooth: Refactor locking in amp_physical_cfm")
