Subject: sigrok: Change 'interval' option to 'MinimumInterval', and allow 0
X-Git-Tag: collectd-5.4.0~14^2~4
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=1a31306f7634710d68d859b5a5d6218c350433c0;p=collectd.git

sigrok: Change 'interval' option to 'MinimumInterval', and allow 0

A MinimumInterval of 0 means whatever the device sends gets dispatched
to collectd. This is the default.
