The context is slightly different here. stmmac_dma_cfg exists once for
each of these ethernet devices in the system, and I would assume that in
the vast majority of cases there's exactly one such device in the system
so the potential size increase is very small. On the other hand, there
are potentially very many struct sched_dl_entity, so the size impact is
multiplied.
Anyway, if you insist I'll rewrite this to use an unsigned int bitfield.
