[PATCH 3.13.y-ckt 35/86] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word
From: Kamal Mostafa
Date: Wed Dec 02 2015 - 18:18:41 EST
3.13.11-ckt31 -stable review patch. If anyone has any objections, please let me know.
------------------
From: David Mosberger-Tang <davidm@xxxxxxxxxx>
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.
