[Arnd Bergmann]

From: Miklos Szeredi <mszer...@redhat.com>

commit 9a232de4999666b2e8ea6775b2b0e3e4feb09b7a upstream.

Without CONFIG_NCPFS_NLS the following warning is seen:

fs/ncpfs/dir.c: In function 'ncp_hash_dentry':
fs/ncpfs/dir.c:136:23: warning: unused variable 'sb' [-Wunused-variable]
   struct super_block *sb = dentry->d_sb;
