Subject: hotplug: ensure that the button subsystem is always registered
X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22http:/www.crowdsec.net/%22/%22https:/collectd.org/%22http:/www.crowdsec.net/%22?a=commitdiff_plain;h=46780098002167070c665f03f1a8ed76d1e1c55f;p=project%2Fprocd.git

hotplug: ensure that the button subsystem is always registered

Its events are handled separately, so there usually is no hotplug.d directory
for it.
