[Linux-NTFS-Dev] [PATCHv3 3/4] fs/buffer: Drop useless return value of submit_bh

[Ritesh H. (IBM) <rit...@gm...>]

submit_bh always returns 0. This patch drops the useless return value of
submit_bh from __sync_dirty_buffer(). Once all of submit_bh callers are
cleaned up, we can make it's return type as void.
