dm writecache: remove BUG() and fail gracefully instead
Building on arch/s390/ results in this build error: cc1: some warnings being treated as errors ../drivers/md/dm-writecache.c: In function 'persistent_memory_claim': ../drivers/md/dm-writecache.c:323:1: error: no return statement in function returning non-void [-Werror=return-type] Fix this by replacing the BUG() with an -EOPNOTSUPP return. Fixes: 48debafe4f2f ("dm: add writecache target") Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
