[PATCH 31/34] brcmfmac: Remove func0 from function array

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

 



Linux doesnt pass you func0 as a function when probing - instead
providing specific access functions to read/write it.

This prepares for a patch to remove the actual array entry itself.
