[PATCH] md: fix oops in error-handling
During early MD setup (superblock reading), we don't have a personality yet. But the error-handling code tries to dereference mddev->pers. Fix. Acked-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
