[PATCH] fbdev: More accurate sync range extrapolation
The EDID block should specify the display's operating limits (vertical and
horizontal sync ranges, and maximum dot clock). If not given by the EDID
block, the ranges are extrapolated from the modelist. However, the
computation used is only a rough approximation, and the resulting values may
not reflect the actual capability of the display. This problem is frequently
encountered when the EDID block has a single entry, the single mode entry will
fail validation.
To prevent this, calculate the values based on the same method used in
fb_validate_mode().
