Subject: [PATCH net-next 38/47] can: netlink: can_changelink(): convert from netdev_err() to NL_SET_ERR_MSG_FMT()
Since commit 51c352bdbcd2 ("netlink: add support for formatted extack
messages") formatted extack messages are supported to inform the user
space or warnings/errors during netlink calls.
Replace the netdev_err() by NL_SET_ERR_MSG_FMT() to better inform the
user about the problem. While there, use %u to print unsigned values
and improve error message a bit.
