NFC: Forward NFC_EVT_TRANSACTION to user space
NFC_EVT_TRANSACTION is sent through netlink in order for a specific application running on a secure element to notify userspace of an event. Typically the secure element application counterpart on the host could interpret that event and act upon it. Forwarded information contains: - SE host generating the event - Application IDentifier doing the operation - Applications parameters Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
