As I mentioned in out-of-band I don't see a huge reason why this can't
be squashed into patch #3.  Logically patch #3 has a bug where it
can't handle setting the chip select without a non-zero transfer and
that bug isn't fixed until patch #4.  ...but if folks really feel like
it should be a separate patch then I won't object too loudly since the
end result is the same.

...so feel free to add:
