#1251636 — [RESEND PATCH] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word

Message-ID<qlEdc-3CF-15@gated-at.bofh.it>
From: David Mosberger-Tang <davidm@egauge.net>

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.
