DMA-API: crypto: fix ixp4xx crypto platform device support
Don't statically allocate struct device's in modules, and shut the warning up with an empty release() function. There's a reason that warning is there and that's not for people to hide in this way. It's there to persuade people to use the correct APIs to allocate platform devices. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
