[PATCH 4.19 159/422] dmaengine: at_xdmac: remove a stray bottom half unlock
From: Greg Kroah-Hartman
Date: Tue Nov 19 2019 - 00:30:39 EST
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
[ 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.
Fixes: d8570d018f69 ("dmaengine: at_xdmac: move spin_lock_bh to spin_lock in tasklet")
