I meant that patch A is broken but (working) patch B applies on top of patch
A so should I submit a patch C to fix patch A, submit a fixed patch A and
then resubmit a patch B against that, or... I'm just unsure of the
development process.

As far as I can tell, the patches aren't applied to any trees yet and are
just sitting in .../gregkh/patches.git. If that's the case, what I would like
is for fix-samsung-brightness-min-max-calculations.patch to be replaced with
the version in https://lkml.org/lkml/2011/4/20/1 and I resubmit a fixed (and
enhanced) add-support-for-samsung-nc210-nc110.patch that applies on top of
it. That way an enhancement patch won't hold up a bugfix patch should there
be any further issues.

I actually wasn't particularly happy with the nc210-n110 patch and was hoping
for some guidance but I think I've managed to implement the workaround
cleanly now so I'll post it in a sec. If you take it and the 2011/4/20/1 one,
great! Otherwise, please let me know what to do. (and sorry for the bother!)

Jason Stubbs
