Subject: [PATCH 6/9] dmaengine: virt-dma: use vchan_vdesc_fini() to free descriptors
Date: Mon, 16 Dec 2019 11:53:25 +0100 [thread overview]
Message-ID: <20191216105328.15198-7-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20191216105328.15198-1-s.hauer@pengutronix.de>
vchan_dma_desc_free_list() basically open codes vchan_vdesc_fini() in its
loop body. Call it directly rather than duplicating the code.
