Well, I'll be...

I like the seq_ stuff, and the ->read() side of things take care of the
issues discussed in this thread. What's even nicer is that if I convert to
that, driver callbacks become something like either:

int driver_show(struct device * dev, struct seq_file * m)

or

int driver_show(struct device * dev, char * buf)


Have you considered doing write()?
