I think at this point however the code is in a state where it would be
more productive to merge it and then fix up the remaining smaller details
than keep going round back to VIA to change it internally and return.
So
Acked-by: Alan Cox <[email protected]> - for the patch series, subject to
further tidyups getting done after it is all merged.

Well, I'm obviously not having any unbiased opinion on this anymore...
... but have a vital interest in getting this driver merged ;)
Joseph: Can you please give me an update about what the current state
of this driver merge is? This message is the last one that I can find
ont this subject on linux-fbdev-devel, and it's already one month old.
Joseph: If there was any further work on this since your last
13-patch-posting in June, can you please provide me with the latest
driver patchset? I'd be happy to help in cleaning this further up and
finally getting it mainline.
Thanks to everyone involved,
