[PATCH] net: ieee802154: mcr20a: do not leak resources on error path

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

 



We already allocated the device and platform  data at this
point. Instead of simply return from the probe function we
need to cleanup the resources first.
