Hi,
we neither received your mail via the mailing list nor our private mail

Please fix this before sending patches out.
But the kernel test bot already demonstrated why this patch is not a good
idea. You can improve it and resent it but I will not accept it in this form.
Kind regards,

If you send a second version then please use `git format-patch -v2 ...` to
format the patch. Now it looks in patchworks like you've resent the first
version again. And please also add a little changelog after "---" which
explains what you've changed. It is trivial in this little patch but still
might be useful.
Regarding the patch: Now you've removed bridge_loop_avoidance.c +
batadv_choose_tt instead of fixing your patch. I would really prefer this
patch version:
https://git.open-mesh.org/linux-merge.git/commitdiff/8864d2fcf04385cabb8c8bb159f1f2ba5790cf71
Kind regards,
Sven

I agree, this patch is better. And I have tested, no sparse warning anymore.
Thank your for your help.
