Subject: [PATCH v3 09/10] dmaengine: edma: Add channel number to debug prints
Date: Mon, 14 Apr 2014 14:42:04 +0300 [thread overview]
Message-ID: <1397475725-5036-10-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1397475725-5036-1-git-send-email-peter.ujfalusi@ti.com>
It helps to identify issues if we have some information regarding to the
channel which the event is associated.
