====================
pull-request: ieee802154-next 2019-11-13

An update from ieee802154 for *net-next*

I waited until last minute to see if there are more patches coming in.
Seems not and we will only have one change for ieee802154 this time.

Yue Haibing removed an unused variable in the cc2520 driver.
