Subject: [PATCH 3/5] dmaengine: bcm2835-dma: Fix memory leak when stopping a running transfer
Date: Fri, 27 Mar 2015 13:35:53 +0200 [thread overview]
Message-ID: <1427456155-28990-4-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1427456155-28990-1-git-send-email-peter.ujfalusi@ti.com>
The vd->node is removed from the lists when the transfer started so the
vchan_get_all_descriptors() will not find it. This results memory leak.
