backports Kconfig processing

backports Kconfig processing

[Arend van Spriel]

Hi Johannes,

I was made aware that the select line in brcm80211 Kconfig is not 
working in backports:

select WANT_DEV_COREDUMP if BRCMFMAC

Is this something that can be fixed in backports?

Regards,
Arend

I guess it can be, but what do you mean by "not working"?

It should be rewritten to

select BPAUTO_WANT_DEV_COREDUMP if BRCMFMAC

but quite possibly the parser doesn't understand the " if BRCMFMAC" part
there.

That exactly what is being reported. Things were working fine until I 
added the "if BRCMFMAC" part.

Yeah, so lib/kconfig.py has this

sel_line = re.compile(r'^(?P<spc>\s+)select\s+(?P<sym>[^\s]*)\s*$')

which doesn't cover the case of "if ..." on the select line.

I guess you could either look at that and fix it - need to fix the regex
to allow all_selects() to find it, and modify_selects() to preserve the
"if ..." part.

Probably something like

Thanks for the suggestion. I will give it a try.
