From f032cfab6158e981a6ea0c369c5366e654e668a6 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Sat, 18 Oct 2014 22:12:47 -0400 Subject: libcacard: introduce new vcard_emul_logout vcard_emul_reset currently only logs NSS out, but there is a TODO for potentially sending insertion/removal events when powering down or powering up. For clarity, this commit moves the current guts of vcard_emul_reset to a new vcard_emul_logout function which will never send insertion/removal events. The vcard_emul_reset function now just calls vcard_emul_logout, but also retains its TODO for watching power state transitions and sending insertion/removal events.
