This patch adds new argument net_device and use netdev private data member
wilc instead of g_linux_wlan, pass dev to the functions also.

Thank you for your advise,
I can use local structure wilc as you said but there are print line inside the function.
The custom print lines will be changed with netdev_xxx format later, so I need to pass dev if necessary.
I used wilc if net_device is unnecessary or unavailable.
For this reason, Is this OK to use net_device if it is necessary?



I've stopped reviewing the series now, odds are all of these need to be
changed in this manner, please do so.

thanks,

greg k-h
