net/compat: Fix minor information leak in siocdevprivate_ioctl() We don't need to check that ifr_data itself is a valid user pointer, but we should check &ifr_data is. Thankfully the copy of ifr_name is checked, so this can only leak a few bytes from immediately above the user address limit. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
