We don't have a client supporting this effort and I don't think the
company I work for would support this effort (maybe it would, but
definitely spread over a long long period), so we're talking about 10-15
working days spread over my free time/week-end, that isn't for in one
month :) I could use help for sure on this driver, that's why I posted
it in staging.

I've done the cleanup on a per-file basis so maybe you looked at one of
the cleaned up files?

Just to be sure, you're telling me that I should post it as is on
linux-wireless and then work with the reviews? Or are you telling me to
take "1 month to clean it up" and then post it on linux-wireless?

Thanks,
Quentin
