Subject: git tracker: override committer/author in commits
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4c7ff2a03b406e1f7820536b3e576d50c1af72f0;p=openwrt%2Fstaging%2Fblogic.git

git tracker: override committer/author in commits

For commits generated by the git tracker, the committer
should always be set to the script, and for those that
are "meta commits" (like failures or backport updates)
the author should also be set to it.
