Thanks Icenowy for confirming!
Jesse: yes, it's perfectly fine to send patches from someone else, as
long as you keep the authorship, their SoB, and add your's.
Typical reasons are lack of time or interest from the original author.
But it's customary to ask the author first, and care should be taken
when changing patches, as this might not be in the interest of the
original author (and they are the ones who will get blamed for bugs).
Also please mark the series either as a Resend or as a v2.
So with Icenowy's confirmation above I consider this fine.
But what was actually holding back this series was lack of review,
testing and/or interest. Similar to Icenowy my personal interest in
crufty old cores is somewhat limited, so this wasn't very high on my
priority list.
So given that there is apparently some interest now:
Can you confirm that you have reviewed the series, or at least tested
this? I would be interested to know if a second pair of eyes had a
look, and to what extent. I don't have any hardware, so would need to
rely on others to make sure this code is somewhat sane.
And it basically looks like a v2 of Icenowy's series, so can you give a
Changelog of the differences? I skimmed over her original series back
then, so I would be interested in what makes this version special.
Cheers,
Andre
