Subject: dnsmasq: switch to ubus-based hotplug call
X-Git-Tag: v21.02.0-rc1~343
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=aed95c4cb8d5a55a795910a759d08e1393f8d967;p=openwrt%2Fopenwrt.git

dnsmasq: switch to ubus-based hotplug call

Use new ubus-based hotplug call in dhcp-script.sh
As sysntpd now makes use of the new ubus-based hotplug calls, dnsmasq
no longer needs to ship ACL to cover ntpd-hotplug.
