But this mean that between the two commit the build will be broken or the 
behavior will change.  Which will break bissections.

For the regulator stuff, I don't want to change the behavior of others board as 
some (mx31lite) enable the regualtor without platform data. That's why I did 
not changed it. 
Moreover for the mc13892 chip (which share the same flag), the probe() does 
modify some registers, so it's not just some cosmetic change, it will change 
the behavior on some boards.

BTW I will be on holydays next week so I won't be able to produce new patches 
soon.

Thanks,

Philippe
