Initial look over the patch looks reasonable; no functionality changes,
just code reduction. That said, I would like to pass it through a quick
validation cycle before its picked up.
We submitted ipw2100-1.1.0 to netdev a month or so ago. I would like to
see it go in to -mm through the netdev tree. I'll ask our QA folks to
run this patch through a quick regression cycle here just to do a sanity
check on it. Assuming nothing comes up, and if Jeff hasn't merged the
ipw2100 code yet, I'll resubmit the ipw2100 driver w/ your patch applied.
Part of the process we have in place is to try and make sure that the
versions that get picked up by distros and the majority of users have a
'known' level of quality. As part of that, we only want to get changes
pushed to -mm and eventual mainline that have gone through regression
testing.
Sound workable?
Thanks,
James
