From: Guennadi Liakhovetski <g.liakhovetski at gmx.de>
On platforms with no support for the shdma dmaengine driver build is
currently failing with
drivers/built-in.o: In function `sh_mobile_sdhi_probe':
drivers/mmc/host/sh_mobile_sdhi.c:170: undefined reference to`shdma_chan_filter'
Fix the breakage by defining shdma_chan_filter to NULL in such

[horms+renesas at verge.net.au: Apply change to shdma-base.h instead of sh_dma.h]

please consider this fix from Guennadi for v3.11 which I have rebased on top of
next-20130709. It fixes a build problem on a number of shmobile defconfigs
Alternatively, I would be happy to take this through the renesas tree.
I posted this patch last week but I'm wondering if you missed it somehow.
This patch resolves a regression in v3.11-rc1.
