Subject: scripts/ubinize-image.sh: fix parameter handling
X-Git-Tag: reboot~6793
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0f39877bacc59049eb0185a93abbcbe23f180bde;p=oweals%2Fopenwrt.git

scripts/ubinize-image.sh: fix parameter handling

ubinize-image.sh previously used ${var:offset:length} substitutions
which are not valid in standard shell.
Replace the existing parameter matching by a case ... esac expression.
