4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 4593403fa516a5a4cffe6883c5062d60932cbfbe ]
cards_found is a static variable, but when it enters atl2_probe(),
cards_found is set to zero, the value is not consistent with last probe,
so next behavior is not our expect.
