Hi Wolfgang,
as you might have noticed the DU440 board is havily based on seuqoia code. Nearly all of your comments apply to that board as well. I thought of the sequoia code as exemplary reference code. And I prefer not to reformat comments when copy and pasting from one board to another.
But if you really insist of these changes I will change the patch.

Please not. The DU440 board will get an updated smi_lynxem driver with support for the SM722 soon. My current hack is to dirty for submission and I just got some more register dumps from SM to support more videomodes. I will need this commented out code to test it. I plan to remove it later.

Hm. So I have to talk with the maintainer of this board - especially how he managed to run this through the custodian without public review. Stefan, how did he bribe you? :-)
But if you really insist of these changes I will change the patch.
Please do. Ideally, please include the Sequoia in your cleanup, too.

Thanks.
One thing I don't like (anymore) though: You patch adds 2 newlines between the functions. I prefer 1 empty line now. Could you please resend the patch with only 1 newline between the functions?
Thanks.

I will update the DU440 patch tonight and also update the sequoia sources in the same manner. So Stefan can lean back :-)
/me leans back and keeps busy with other high priority stuff. :)
You should not lean back! There are a couple of coding style issue's in makalu.c and kilauea.c (very long lines, comment format). I cannot understand how these files made it into the repository:-)
