Subject: scripts/kernel_bump: Improve omitted version error
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ed896c32b09e3adfaa5fdda5c584ef776e395b09;p=openwrt%2Fstaging%2Fthess.git

scripts/kernel_bump: Improve omitted version error

If a version string was not supplied, we currently print an empty
string. We can do better here. Also by popular demand, print the usage
information in case of error.
