Hi Mauro,

Thank you for the patch.

The omapfb driver doesn't include any asm/ header, so it should probably build 
fine on non-ARM architectures. Instead of adding stubs here, you can enable 
compilation of the driver on all platforms, in which case the omap_vout driver 
could keep depending on FB_OMAP2 as it should.
