Thanks. Have you submitted this patch upstream? This is more-and-less a
feature patch, and in Buildroot, we don't like too much carrying
feature patches if we don't believe they will be merged upstream.

Of course, if it has been submitted upstream and received what seems
like a positive feedback, it's perfectly fine to take it in Buildroot
until upstream makes a new release.

Thanks!

Thomas

Yes, patch already proposed upstream, see https://bugs.freedesktop.org/show_bug.cgi?id=70356

Let's wait awhile for upstream comments...

Thanks,

Peter

In the mean time Peter (there's too many Peters in this discussion)
Hutterer has closed it as WONTFIX, so I'm afraid I'll have to disappoint
and say no..
