What matters is if the original authors of the old st7701 driver are
around and reviewing and testing patches at all. What we need is
active maintainers. (Added Jagan, Marek & Maya).

I buy the reasoning that the st7701s is perhaps substantially different
from st7701.

If st7701s is very different then I suppose it needs a separate driver,
then all we need to to name the driver properly, i.e.
panel-sitronix-st7701s.c.
