Heh... IIRC, I tried to fix a lot of this messages (in U-Boot), around
a year ago, and we decided to not apply them in u-boot, instead they
should go away via kernel resyncs, when the warnings are fixed in the
kernel!

Also I think, I tried a similiar approach as the commit you mentioned...
Ah, yes, here:
http://lists.denx.de/pipermail/u-boot/2016-April/252408.html

We decided (for u-boot) it would be better to fix the problems and
not supress the warning, but it seems, the problems get not really fixed
in the kernel ...

I wasn;t aware of the above patch in the kernel... thanks for pointing!

@Tom:
So, I feel, the problems get not fixed fast in the kernel (if ever),
may we want to cherry-pick this patch from the kernel (or make a
similiar patch for U-Boot)?

bye,
Heiko
