Subject: [PATCH] md: fix build failure for !MODULE
Git-commit: 2198c51a08349eb176cb9789bef6f7243b8699f8
Patch-mainline: v6.0-rc1
References: jsc#PED-2766
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=unused-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")
Make mddev_find() available only for non-modular builds.
