Hmm, I probably didn't actually. :s

I guess the bisecting process etc. for this repos must be a bit
different to other areas? Would I need a full make clean and recompile
at each stage of a bisect (not that it takes all that long).

Hmmm, OK. Any page describing how to do this anywhere? e.g. how to
clone, bisect etc. on older versions of the drivers?

Trying to find out the details of how to debug and bisect alsa drivers
seems to be pretty hard (and I don't consider myself a total noob here,
tho' it feels like it!)

Thanks for any insights :)
