Fix the typo: OD_RELAYMODE->OD_CFG

Hi, Matthias
Thanks for your reply.

Although it is quite clear what the patch does, could you write one
sentence to explain what it does. Maybe explain even which effect it
has, which error get fixed etc.

Ok, I will do that.

As we are getting public available boards now, we should take more care
about fixes. If you have a fix for a commit introduced in an earlier
version of linux and it should be fixed for this version as well (e.g.
v4.6 does have the feature but it does not work correctly) then please
add these two lines before your Signed-off-by:
Fixes: <commit-hash> ("<commit subject line>")
Cc: stable@xxxxxxxxxxxxxxx # v4.6+

Where v4.6+ stands for the oldest version where this should get fixed.

Ok, but the patch hasn't been merged into v4.8 (just in drm-next [1] and
linux-next [2]), how can I mark that?

If the commit get's into v4.9 then make sure that this patch get's merged into the fixes for v4.9 by the corresponding maintainer.



Thanks a lot,
