[PATCH] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word.

[PATCH] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word.

[David Mosberger-Tang]

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.

Thanks for having rewritten this patch! It's much more simple like this ;-)

Applied "spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word" to the spi tree

[Mark Brown]

The patch

   spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word

has been applied to the spi tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
