Subject: [PATCH] sd-device: fix device_get_properties_strv()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A NULL pointer was inserted as the first element of the strv.

This had the effect of always passing the empty environment to processes
spawned by udev.

Reported by Michał Bartoszkiewicz.

(cherry picked from commit 0e3e60561395a8dd0464f9427d7fc9209bf3b007)
