[PATCH 3/7] rtl28xxu: do not return error for unimplemented fe callback

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

 



Use of frontend callback is highly hardware design dependent
and whole callback could be optional in many cases. Returning
error by default when callback is not implemented is stupid.
