When CONFIG_NCPFS_NLS is not set, we get a harmless warning about an unused local variable, because that is only passed into a macro that does not evaluate its argument:
fs/ncpfs/dir.c:136:23: warning: unused variable 'sb' [-Wunused-variable]
This replaces the trivial macro with an equally trivial inline function, which avoids the warning.
