mac802154: declare struct ieee802154_ops as const
The ieee802154_ops structure should be never changed during runtime. This patch declare this structure as const to avoid a runtime change. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Cc: Alan Ott <alan@signal11.us> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
