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

Hi all,

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

In file included from include/linux/io.h:13,
                 from drivers/soc/apple/mailbox.c:22:
drivers/soc/apple/mailbox.c: In function 'apple_mbox_send':

      |                            ^~~~~~~~~

Caused by commit

  0d1f3f7f8486 ("soc: apple: mailbox: Add ASC/M3 mailbox driver")

I have used the asshi-soc tree from next-20230602 for today.
