Subject: base-files: exit if mtd write command fails during sysupgrade
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5b2e20807d2b38de1cc4185d15bb4320b8bd743a;p=openwrt%2Fstaging%2Fxback.git

base-files: exit if mtd write command fails during sysupgrade

It avoids confusing situations like:
> Could not get image magic
> Image check failed.
> Upgrade completed
> Rebooting system...
