no, but this isn't our problem. Our branch is based on bluetooth-next.
It could be that this fix is already solved in other repository, if you
want to fix it you need to find out if it already fix and create some
patch.

I will show you a how to which I would do that:

1) check current next tree (sometimes there exists also special repos
like for bluetooth, check https://git.kernel.org/cgit/linux/kernel/):

https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/drivers/of/platform.c

this shows the log of this file.

"of/platform: Fix microblaze build failure" - sounds like a build issue.
Click on it you get:

https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/of/platform.c?id=e1319ea5db6dee48b7fa3a5822c3940dc649ee6a

so, it's already fixed.

The linux-wpan-next branch is based on bluetooth-next and we are a
little far behind on everything which isn't the net branch.

2)
If 1) doesn't show any fix then ask on the mailinglist.

./scripts/get_maintainer.pl -f drivers/of/platform.c

Grant Likely <grant.likely@linaro.org> (maintainer:OPEN FIRMWARE AND...)      
Rob Herring <robh+dt@kernel.org> (maintainer:OPEN FIRMWARE AND...)
devicetree@vger.kernel.org (open list:OPEN FIRMWARE AND...)
linux-kernel@vger.kernel.org (open list)

there you can find the necessary people which working on this branch.



So now if you want to fix it for your working branch, then add in your
git remotes the linux-next repository and run "git cherry-pick
e1319ea5db6dee48b7fa3a5822c3940dc649ee6a", but please don't send patches
for this fix to me then. ;)

Hi Alex,

Thanks for the info on finding the maintainers, I'm sure this will come in useful in the future.  I found the patch I needed, thanks again :)
