[PATCH 12/14] init: move cifs_root_data() prototype into linux/mount.h

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

cifs_root_data() is defined in cifs and called from early init
code, but lacks a global prototype:

fs/cifs/cifsroot.c:83:12: error: no previous prototype for 'cifs_root_data'

Move the declaration from do_mounts.c into an appropriate header.
