The usual conversions.
These are intended to be merged to net-next directly,
because bluetooth tree is missing one of the pre-req
changes at the moment.
v2: s/got/go/
Jakub Kicinski (2):
bluetooth: use eth_hw_addr_set()
bluetooth: use dev_addr_set()

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it go through appropriate helpers.
Convert bluetooth from memcpy(... ETH_ADDR) to eth_hw_addr_set():
