Subject: init: move cifs_root_data() prototype into linux/mount.h
Date: Wed, 17 May 2023 15:11:00 +0200

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.
