Subject: treewide: remove obsolete sysupgrade watchdog kill
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c4ac02ffca4e8b9ffe8c702abf4de4063d3097e6;p=openwrt%2Fstaging%2Fstintel.git

treewide: remove obsolete sysupgrade watchdog kill

The watchdog kill command was meant for busybox watchdog. Busybox watchdog
was replaced by the procd watchdog mid 2013 with commit df7ce9301a25
("busybox: disable the watchdog utility by default"), which makes the kill
command obsolete since quite some time.
