Subject[PATCH v2 4/7] Input: elantech - remove ETP_EDGE_FUZZ_V2
Date
Don't try to be too clever and remove ETP_EDGE_FUZZ_V2. X, Y ranges
should be just the raw resolution of the device. Otherwise, they can
cause underflow on the Y axis.

- * It seems the resolution for hardware version 2 doubled.
- * Hence the X and Y ranges are doubled too.
- * The bezel around the pad also appears to be smaller
+ * The resolution for older v2 hardware doubled.
