Subject: networkd: don't assume udev_device_new_from_device_id sets errno
X-Git-Tag: v216~353
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=2b49732c3d511007ae2c413997e56c40f678d79a

networkd: don't assume udev_device_new_from_device_id sets errno

This reverts 6f4d55a8ae04e344a41fc2adef12ad99c2bb2927, as we cannot rely on errno here.
