Subject: package/comgt: Handle bind/unbind events
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=89ef883b92b3a87d9ab1bd289de26b9e72681dac;p=openwrt%2Fstaging%2Fthess.git

package/comgt: Handle bind/unbind events

This script was expecting only add/remove events which has not been the
case since Kernel 4.12 (which added bind/unbind). Bind events were getting
treated as remove events which would cause hotplugged 3g modems to not
work.
