Hi all,

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

drivers/md/md.c:717:22: error: 'mddev_find' defined but not used [-Werror=
=3Dunused-function]
  717 | static struct mddev *mddev_find(dev_t unit)
      |                      ^~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  4500d5c17910 ("md: simplify md_open")

I have applied the following patch for today.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Thu, 21 Jul 2022 13:03:16 +1000
Subject: [PATCH] fix for "md: simplify md_open"
