Subject: [ARM] Use core_initcall() to initialise ARM DMA
X-Git-Tag: v2.6.16-rc1~929^2~29
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=6842b9299272a9471a7e94e046b953f6ffe3db9d;p=linux-2.6-omap-h63xx.git

[ARM] Use core_initcall() to initialise ARM DMA

There's no need to have DMA initialised at the same time as
interrupts.  Move it to a core_initcall().
