[Buildroot] [PATCH 2/3] nanopb: Init at 69e9c1fc8162956feffa32e07a97c53bdb92f5ef

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

Thanks for this new iteration. However, there's a big problem with your
patch: it seems to be corrupt, and therefore cannot be applied. That's
weird because you've used git send-email, which normally always get
things right, but not here:

The copy of the patch that failed is found in: .git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.

And indeed, looking at your patch below, some lines have been wrapped.

The commit title should be just:

	nanopb: new package

Those two lines should be removed.

Here the line is wrapped while it should not.

This comment is not needed.

How is this comment related to the below dependencies? Your comment
mentions a host tools, but you don't depend on any host package. I know
'protobuf' depends on 'host-protobuf', which will bring you the host
protoc, but that's not very clear from your comment.

Line has been wrapped.

This looks really really weird, I'll review PATCH 3/3 to try to
understand, but this approach doesn't seem very good. Also, this
paragraph has also been badly rewrapped when your patch was sent.
