Looks reasonable. The AO speed checks were added to the NI drivers (in
the out-of-tree Comedi sources before they were imported into "staging")
in early May 2007 but probably weren't tested to the limits.
Actually I've also used the git history from the out-of-tree sources,
but mistook in how to use git blame!
After looking at it again, the 357 value was introduced in 2005 in
(commit 6d063feea3). At this time AO was not supported yet, so it was
just commented out (which also means probably not tested). In 2007,
commit 4a31ee5f added AO support for the driver and the value just got
uncommented. It might not have been tested either at this time, as many
other boards with different (and working) values were also available.
So all in all, the version history doesn't say enough, but it could well
be that maximum AO rate had never been tested on this board. Now it's
done :-)
(I'll make the same change to the out-of-tree Comedi sources on
www.comedi.org.)
Great! BTW, do I understand correctly that it's better to write patches
for the staging tree, instead of the out-of-tree sources?
In any way, thanks for reviewing the patch Ian!
