Subject: [PATCH 6/6] virtpm: Fix @path handling in virTPMEmulatorInit()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This function finds "swtmp", "swtpm_setup" and "swtpm_ioctl"
binaries in $PATH and stores resolved paths in global variables
so that they can be obtainer later. Anyway, the resolved path is
marked as g_autofree and to avoid its freeing later on in the
function the variable is set to NULL manually. Well, we have
g_steal_pointer() for that.
