Subject: linux-next: build failure after merge of the dmaengine tree

Hi all,

After merging the dmaengine tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  b127315d9a78 ("dmaengine: apple-admac: Add Apple ADMAC driver")

I have used the dmaengine tree from next-20220609 for today.
