It's a subjective thing and often a matter of maintainer taste. I can
say that after contributing to various Linux subsystems. If you split a
similar patch for MTD subsystem you'll get complains about making
changes too small & too hard to review (sic!).

This isn't a bomb really: 63 insertions(+), 48 deletions(-)

That said I admit I don't know MIPS tree habits. Thomas: do you prefer
smaller patches in case like this?
