Subject: [PATCH] dmaengine: at_xdmac: remove a stray bottom half unlock
Date: Fri, 3 May 2019 16:15:07 +0300 [thread overview]
Message-ID: <20190503131507.GA1236@mwanda> (raw)
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")
