Yes, after the first few hours I got lazy. Obviously, linux-next
doesn't build with CONFIG_OMAP2_DSS_DEBUG_SUPPORT (or may not build OSS2
at all), so it didn't catch them either.

I've fixed it (probably tomorrow's linux-next), but hope that the
introduction of a 'bool' in that header doesn't break anything else.

Please post fix if it does. Though I think the new hotness is dev_debug
and dynamic debugging.

Thanks!
Rusty.
