There's 2 typos in the subject line (s/hldcd/hlcdc/ and
s/removed/remove/), and you're removing an empty line after
atmel_hlcdc_crtc_create() definition (which is correct, but I'm not
sure it should be part of the same patch).
Otherwise it looks good to me.
Once you've fixed those 2 things, you can add my

Thanks Boris.

@Daniel, do you want me to resend this patch or will you fix it directly in mode-fixup git branch?

Oops, I forgot to answer to that one. I'm fine with the extra space
removal too, you can apply it.

You should try to avoid mixing code style fixes with functional
changes but in case of gma500 it's hard to resist. No need to change
this.

This might already have been merged but if not:
