Could you please tell me what difference this makes? It looks like source churn 
rather than a substantive change. The symbol is defined in pci.h and is used in 
many architures. Certainly, PCIBIOS_SUCCESSFUL indicates success even more 
clearly than 0 does.

Why is your name inside quotes in your s-o-b?

It's required for a proper email header if you have a dor (.) in your cleartext
name, but it is not required in a Signed-off-by tag, though a number of people
still do it out of habit. I'm sure it's fine either way.

Thank you for the explanations. The cover letter did help.

It is a trivial first step towards a probably significant task. I 
explained in the Cover Letter, I can see it didn't get through but I Cc 
linux-wireless (properly this time). Probably, too many addresses.

I have resent it. It is here

I saw people with >2 names do it, so I did! Please let me know if it is odd.
