[PATCH v7 6/7] wifi: wilc1000: Register wiphy after reading out chipid

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

 



Register wiphy after reading out chipid, so the chipid can be
used to determine chip features and not advertise WPA3/SAE
support to userspace on WILC3000. Note that wilc_netdev_cleanup()
will deregister the wiphy in fail path.
