From 8a49943f5bc5ff4f835d50451ecf2380eab44d2e Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sun, 25 Oct 2015 22:54:24 +0100 Subject: NFC: nci: Call nci_hci_clear_all_pipes at HCI initial activation. When session_id is filled to 0xff, the pipe configuration is probably incorrect and needs to be cleared.
