[PATCH] fs/ncpfs: Fix a build warning when CONFIG_NCPFS_NLS is not set

Show all headers | View raw

From: Borislav Petkov <bp@suse.de>

I get this when doing randconfig builds:

  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;

because NCP_IO_TABLE macro is NULL in the !CONFIG_NCPFS_NLS case and @sb
remains unused then.

Sticking it into the macro directly takes care of the warning and the
code is still readable. :)
