@@ -96,9 +96,8 @@ value to be exported. Some types can have different widths on different
architectures, though, complicating the situation somewhat. There is a
function meant to help out in one special case:
- struct dentry *debugfs_create_size_t(const char *name, umode_t mode,
- struct dentry *parent,
- size_t *value);
+ void debugfs_create_size_t(const char *name, umode_t mode,
+ struct dentry *parent, size_t *value);
As might be expected, this function will create a debugfs file to represent
a variable of type size_t.
