Hi Andy, thanks for the review! Looking the kernel code for some similar
parameters, I couldn't see any better alternative (like a helper) to do
this parsing - checked for example the ftrace parameters (borrowed my
code from there, in fact heh), initcall_blacklist, module_blacklist,
usbcore.quirks, etc.

I'll try to follow your suggestion, to reduce a bit the code...though I
confess the original code reads more clearly for me.

Cheers,


Guilherme
