3.2.84-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Guenter Roeck <[email protected]> commit 8e4b72054f554967827e18be1de0e8122e6efc04 upstream. Since commit acb2505d0119 ("openrisc: fix copy_from_user()"), copy_from_user() returns the number of bytes requested, not the number of bytes not copied.
