Subject: [PATCH 3.18 108/134] net: set static variable an initial value in atl2_probe()

3.18-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.
