  • [PATCH v3 01/19] byteorder: Move {cpu_to_be32,be32_to_cpu}_array() from

    From Mika Westerberg@21:1/5 to All on Mon Oct 2 12:50:02 2017
    We will be using these when communicating XDomain discovery protocol
    over Thunderbolt link but they might be useful for other drivers as
    well.

    Make them available through byteorder/generic.h.
