4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Takashi Iwai <[email protected]> commit 3a72494ac2a3bd229db941d51e7efe2f6ccd947b upstream. The timer user status compat ioctl returned the bogus struct used for 64bit architectures instead of the 32bit one. This patch addresses it to return the proper struct.
