HID: hiddev: potential info leak in hiddev_ioctl()
Smatch has a new check for Rosenberg type information leaks where
structs are copied to the user with uninitialized stack data in them.
In this case, the hiddev_devinfo struct has a two byte hole.
struct hiddev_devinfo {
__u32 bustype; /* 0 4 */
__u32 busnum; /* 4 4 */
__u32 devnum; /* 8 4 */
__u32 ifnum; /* 12 4 */
__s16 vendor; /* 16 2 */
__s16 product; /* 18 2 */
__s16 version; /* 20 2 */
/* XXX 2 bytes hole, try to pack */
__u32 num_applications; /* 24 4 */
