Subject[PATCH 3.19.y-ckt 056/164] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word
Date
3.19.8-ckt11 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Mosberger-Tang <davidm@egauge.net>

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.
