[Libosinfo] [PATCH 3/3] installer: API to query device driver signing requirement

From: "Zeeshan Ali (Khattak)" <zeeshanak at gnome.org>
Some OS vendors recommend or require device drivers to be signed by them
before these device drivers could be installed on their OS. This
recommendation/requirement then also applies to the installer scripts of
that particular OS.
This API enables apps to query such requirement/recommendation, if any.
