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

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).
