Subject: [PATCH 08/33] NFC: Factorize HCI cmd completion
Date: Fri, 6 Jul 2012 22:09:28 +0200 [thread overview]
Message-ID: <1341605393-32056-9-git-send-email-sameo@linux.intel.com> (raw)
In-Reply-To: <1341605393-32056-1-git-send-email-sameo@linux.intel.com>
From: Eric Lapuyade <eric.lapuyade@intel.com>
HCI cmd can be completed either from an HCI response or from an
internal driver or HCI error. This requires to factorize the
completion code outside of the device lock.
