staging: android: ion: check for kref overflow This patch is against 4.9. It does not apply to master due to a large rework of ion in 4.12 which removed the affected functions altogther. 4c23cbff073f3b9b ("staging: android: ion: Remove import interface") Userspace can cause the kref to handles to increment arbitrarily high. Ensure it does not overflow. Signed-off-by: Daniel Rosenberg <drosen@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
