From de054799b7ffee8ce1e3971a8dcd7816ccf04977 Mon Sep 17 00:00:00 2001 From: Ilan Elias Date: Thu, 22 Sep 2011 11:13:01 +0300 Subject: NFC: implicitly deactivate in nci_start_poll When start_poll is called, and a target was implicitly activated, we need to implicitly deactivate it. On the other hand, when the target was activated by the user, we should not deactivate it. Signed-off-by: Ilan Elias Acked-by: Lauro Ramos Venancio Signed-off-by: John W.
