Hi,
It seems I have not added description to this patch.
In this patch porch is calculated in compatible way to
drm_display_mode_from_videomode core function.
The way it was seems to me incorrect and it did not work on my hw.
Anyway this patch could be merged with Sean's patches, if he agrees.
Regards
Andrzej
