Subject: [PATCH bluetooth-next 2/9] at86rf230: add missing error handling
Date: Tue,  7 Oct 2014 10:38:26 +0200	[thread overview]
Message-ID: <1412671113-26675-3-git-send-email-alex.aring@gmail.com> (raw)
In-Reply-To: <1412671113-26675-1-git-send-email-alex.aring@gmail.com>

This patch adds an async error handling function if sync state change
runs into a timeout. The async error handling function tries to recover
the phy state machine into a valid state.
