You do not need make this a conditional, if sdata->prop.max_x or
sdata->prop.max_y is 0 is it OK.
However, there is a slight problem: you call hw_init() on resume,
potentially updating prop.max_x and prop.max_y and taking them out of
sync if they have been overridden by the DT data and
touchscreen_parse_properties(). I think it would be best if
s6sy761_hw_init() had 2 additional arguments for max_x and max_y and you
passed them to input_set_abs_params() and left sdata->prop to be managed
solely by touchscreen_parse_properties().
Also, is everything in s6sy761_hw_init() needed at resume time?
Thanks.
