>From 94c4769d2171ce66079fd486a45e09dd64db62c0 Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Sat, 19 Dec 2015 15:26:23 +0000 Subject: [PATCH] ata: sata_dwc_460ex: remove incorrect locking This lock is already taken in ata_scsi_queuecmd() a few levels up the call stack so attempting to take it here is an error. Moreover, it is pointless in the first place since it only protects a single, atomic assignment.
