Subject: [PATCH 24/25] p11_child: check if card is present in wait_for_card()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some implementations of C_WaitForSlotEvent() might return even if no
card was inserted. So it has to be checked if a card is really present.
