Subject: perl plugin: Fixed an "unused variable" warning.
X-Git-Tag: collectd-4.2.0~44
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=03f3b203fe0673c17259fb4230f56bf82cb81f6e;p=collectd.git

perl plugin: Fixed an "unused variable" warning.

When compiling with debugging disabled, gcc complained about an unused
variable in init_pi(). -Werror thus caused the build to fail.
