[PATCH v2] net: set static variable an initial value in atl2_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



cards_found is a static variable, but when it enters atl2_probe(),
cards_found is set to zero, the value is not consistent with it in the heap,
so next behavior is not our expect.

 v1->v2 change the subject from "net: drop pointless static qualifier in atl2_probe()"
 to "net: set static variable an initial value in atl2_probe()";
 keep 'static' for variable cards_found.
