Various boot failures on non-tegra platforms (sunxi, omap) started
showing up in next-20150522, and still exist in next-20150525[1] and
today I bisected them down to this patch.

I didn't look closely, but I"m guessing the module_init() function
here needs some compatible checking so it's not actually executed on
non-tegra platforms.

I confirmed that reverting this patch on top of next-20150525 gets
both the sunxi and omap platforms booting again.
