[PATCH 15/21] USB: serial: omninet: simplify endpoint check

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

 



Simplify the endpoint sanity check by letting core verify that the
required endpoints are present.

Note that the driver uses the second bulk-out endpoint for writing.
