4.2.8-ckt1 -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.
