clang complains about casting pointers to smaller enum types.

P.S. I fixed a similar issue in v5, but it was in another patch, and the
test robot only complains about the first issue, so I missed this one.

There is a similar warning in ltc2941-battery-gauge, let me know if I
should submit a fix for it as well.
