Date: Tue, 25 Oct 2022 12:02:54 +0300 From: Tudor Ambarus <tudor.ambarus@...rochip.com> To: <vkoul@...nel.org>, <peda@...ntia.se>, <du@...ntia.se> CC: <maciej.sosnowski@...el.com>, <nicolas.ferre@...rochip.com>, <mripard@...nel.org>, <torfl6749@...il.com>, <linux-kernel@...r.kernel.org>, <dmaengine@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, "Tudor Ambarus" <tudor.ambarus@...rochip.com> Subject: [PATCH v2 20/32] dmaengine: at_hdmac: s/atc_get_bytes_left/atc_get_residue Use dmaengine terminology and rename the method to better indicate what it does: it gets the residue value which will be later on set with dma_set_residue().
