And in this case, it should probably be smartcard_reader_free()
(otherwise I expect _ref to exist!)

We usually use verbs after the name, like smartcard_reader_unref.

I think the ack from Marc-andre is still valid, nothing against it.

[Spice-devel] [spice-gtk v2] smartcard: Warn if multiple readers are detected

2019-02-22 Thread Christophe Fergeau 
spice-server does not deal properly with multiple smartcard readers,
only the first one will be working. Add a warning when this happens to
make it easier to diagnose such issues.

Alternate version using g_list_length rather than manually counting the
elements.
