Tobias,

What you want wouldn't be always what someone wants. This patch is really a trivial thing and as I already commented I thought as-is enough.
Even I already picked your suggestion up,
"For 'pipe_clk' I would just go with this:
@pipe_clk: A pointet to the crtc's pipeline clock"

And I never ignore you. Instead I commented like below for you,
"If you want to update the description more then you can post it"

Thanks,
