It's not for testing, more for code review and to help understand the code [though
as you say, we do need to ensure that each commit doesn't actually break the 
build]. 
Right now, the driver code goes in as a single commit - which makes it a hard
enough task to review and see what is in there. One suggestion that hopefully
wouldn't be too much work might be to split the code up into: basic device
init code, RX and TX functions, and then any additional features based on top
of that [ideally one patch per added feature].
