Subject: do_rrdtool_update_data: Initialize data buffer
X-Git-Url: http://git.itanic.dy.fi/?p=rrdd;a=commitdiff_plain;h=f13cd695441badd24d4a9e52b8e917baf8caf2d8

do_rrdtool_update_data: Initialize data buffer

Make sure the data buffer is zeroed completely before use. This
silences a walgrind warning of uninitialzed data usage.
