I did some tests yesterday, and compilation of this driver also broke
on other archs.

So, I removed COMPILE_TEST:
	http://git.linuxtv.org/cgit.cgi/mchehab/media-next.git/commit/

We may be able to re-enable if someone do some work on this driver for
it to use the standard DMA API, instead of an omap-specific one.

Btw, I had to do a similar patch also for OMAP1 driver sometime ago:

commit 4228cd5682f07b6cf5dfd3eb5e003766f5640ee2
Author: Mauro Carvalho Chehab <m.chehab@samsung.com>
Date:   Tue Sep 9 14:55:15 2014 -0300

    [media] disable COMPILE_TEST for omap1_camera
    
    This driver depends on a legacy OMAP DMA API. So, it won't
    compile-test on other archs.
    
    While we might add stubs to the functions, this is not a
    good idea, as the hole API should be replaced.
    
    So, for now, let's just remove COMPILE_TEST and wait for
    some time for people to fix. If not fixed, then we'll end
    by removing this driver as a hole.
