Hi all,

After merging the mm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from fs/btrfs/tree-checker.c:20:
include/linux/error-injection.h: In function 'get_injectable_error_type':
include/linux/error-injection.h:22:17: error: 'EOPNOTSUPP' undeclared (first use in this function)
   22 |         return -EOPNOTSUPP;
      |                 ^~~~~~~~~~
include/linux/error-injection.h:22:17: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  fcb9954aa1dc ("error-injection: remove EI_ETYPE_NONE")

I have reverted that commit for today (and the following one).
