Message-Id: <faed3a9b791845428adb337313a566ffbcaba4d6.1456308281.git.jslaby@suse.cz> Date: Wed, 24 Feb 2016 11:03:27 +0100 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, David Mosberger-Tang <davidm@...uge.net>, Nicolas Ferre <nicolas.ferre@...el.com>, Mark Brown <broonie@...nel.org>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 012/142] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word From: David Mosberger-Tang <davidm@...uge.net> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 06515f83908d038d9e12ffa3dcca27a1b67f2de0 upstream. The DMA-slave configuration depends on the whether <= 8 or > 8 bits are transferred per word, so we need to call atmel_spi_dma_slave_config() with the correct value.
