    clang warns about overflowing the data[] member in the struct pnpipehdr:
    net/phonet/pep.c:295:8: warning: array index 4 is past the end of the array (which contains 1 element) [-Warray-bounds]
                            if (hdr->data[4] == PEP_IND_READY)
                                ^         ~
    include/net/phonet/pep.h:66:3: note: array 'data' declared here
                    u8              data[1];
    Using a flexible array member at the end of the struct avoids the
    warning, but since we cannot have a flexible array member inside
    of the union, each index now has to be moved back by one, which
    makes it a little uglier.
