Applied "spi: spi-pxa2xx: Remove unused legacy null dma buffer and allocation for it" to the spi tree

[Mark Brown]

The patch

   spi: spi-pxa2xx: Remove unused legacy null dma buffer and allocation for it

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

This doesn't apply against current code, please check and resend.

Hmm... I'm confused, both patches were done on top of commit 
34cadd9c1bcb ("spi: pxa2xx: Add support for Intel Sunrisepoint") in 
spi/topic/pxa2xx and I see this patch 1/2 applied there and merged into 
for-next now. Anyway, patch 2/2 should still apply fine.

It didn't apply when I tried it yesterday.
