#1423828 — [PATCH] dm raid: don't use 'const' in function return

FromArnd Bergmann <arnd@arndb.de>

Subject[PATCH] dm raid: don't use 'const' in function return
Message-ID<rKBtg-6qC-25@gated-at.bofh.it>
A newly introduced function has 'const int' as the return type,
but as "make W=1" reports, that has no meaning:

drivers/md/dm-raid.c:510:18: error: type qualifiers ignored on function return type [-Werror=ignored-qualifiers]

This changes the return type to plain 'int'.
