From 8edddc2cf3c1f8b96708df55e478d2181029f437 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 3 May 2019 16:15:07 +0300 Subject: [PATCH] dmaengine: at_xdmac: remove a stray bottom half unlock [ Upstream commit 0b515abb6b7eb08e90bdfc01fc8fbdd112c15d81 ] We switched this code from spin_lock_bh() to vanilla spin_lock() but there was one stray spin_unlock_bh() that was overlooked. This patch converts it to spin_unlock() as well.
