Sure. I can strip out the others and resend if you'd like, or you
could just commit the parts you think are appropriate. I don't imagine
there would be any ill effects from including the patch for files like
 src/atombios_output.c            |    2 +-
 src/drmmode_display.c            |    6 +-
though. This wasn't a blind find'n'replace, so the ones included
should be pretty good.

Thanks,
Matt
