[PATCH net-next 2/6] ocelot: Refactor common ocelot probing code to ocelot_init

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

 



This is just common path code that belogs to ocelot_init,
it has nothing to do with a specific SoC/board instance.
Add allocation err check in the process.
