Subject: procd: fix/clean some conditions in nand.sh
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=db69761f9494ca3ebb7ebb559872809de061d973;p=openwrt%2Fstaging%2Frobimarko.git

procd: fix/clean some conditions in nand.sh

1) nand_upgrade_tar: use a simpler condition that matches if () { }
   logic and fix check of $kernel_length variable
2) nand_do_upgrade_stage2: use case, otherwise one could believe we
   always call nand_upgrade_tar
