Subject: layerscape: mkits-multiple-config: fail on invalid arguments
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b8bbac951c42c6639a66696ade4477aa2be6aa54;p=openwrt%2Fstaging%2Fansuel.git

layerscape: mkits-multiple-config: fail on invalid arguments

Fail if arguments couldn't be parsed and print unrecognized part. It's
important when running it from script with dynamic values. Missing value
could result in skipping argument and silent failures (unexpected its).
