HID: hidraw: add compatibility ioctl() for 32-bit applications.
Added the ioctl function to the compat_ioctl pointer in the file_operations struct. Before this, some ioctls would fail for 32-bit apps on 64-bit systems. Signed-off-by: Alan Ott <alan@signal11.us> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
