Thanks Stephen,

This should have depends on ARCH_MXS at least and should not have built
for x86_64. Below patch should fix it and I will apply this.

I had this series pending and wanted to get this merged but it didn't
apply for me last week and I was out for the long weekend :(
So merged on first chance I got back.

Tree is frozen now, barring any other hiccups. Sorry for the issue

Subject: [PATCH] dmaengine: imx: fix the build failure on x64

commit 6bd081277ea0 "dmaengine: imx-dma: merge old dma-v1.c with
imx-dma.c" removed the dependency in config for the imx dma driver,
whereas it should depend on ARCH_MXS
