Subject: [PATCH] dmaengine: apple-admac: Fix grabbing of channels in of_xlate
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
The of_xlate callback is supposed to return the channel after already
having 'grabbed' it for private use, so fill that in.
Fixes: b127315d9a78 ("dmaengine: apple-admac: Add Apple ADMAC driver")
