From 352a5f5fb3ad8f829cfd4248fe6119895bda881f Mon Sep 17 00:00:00 2001 From: Eric Lapuyade Date: Fri, 19 Jul 2013 14:57:55 +0200 Subject: NFC: netlink: Add result of firmware operation to completion event Result is added as an NFC_ATTR_FIRMWARE_DOWNLOAD_STATUS attribute containing the standard errno positive value of the completion result. This event will be sent when the firmare download operation is done and will contain the operation result.
