+ data_present = touchscreen_get_prop_u32(np,
"touchscreen-size-x",
+
input_abs_get_maximum(axis),
+ &maximum) |
+ touchscreen_get_prop_u32(np,
"touchscreen-fuzz-x",
+
input_abs_get_fuzz(axis),
+ &fuzz);
+ if (data_present)
+ touchscreen_set_params(dev, axis, maximum, fuzz);
Umm. So you are changing behaviour from "whatever was there" to
"input_abs_get_maximum"... in n900 case. Is that a good idea for a
regression fix this late in release cycle?
Maxime's patch should be easy to fix...
