The main case here is that it's easy to review during upstreaming and
in case of somebody looking into the history. It keeps each of the
changes logically isolated. I.o.w. it adds flexibility, for example
changing ordering of the WDT and LED patches in the series in this
case.
I admit that for _this_ series my arguments are not strong, but I'm
speaking out of general approach. The pattern
1) add new api
2) switch driver #1 to it
...
2+n) switch driver #n to it
3+n) drop old API
is how we do in the Linux kernel, even if the changes are coupled
together from a functional / compile perspective.
