Subject: [PATCH AUTOSEL 4.19 128/205] dmaengine: at_xdmac: remove a stray bottom half unlock

From: Sasha Levin <[email-masked]>

[ 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")
