Input: cyttsp - use PTR_ERR_OR_ZERO()
The PTR_ERR_OR_ZERO() helper function checks if a pointer contains an
errno code and returns it or return 0 if that's not the case. Use the
helper instead of open coding the same logic in the driver. This was
found with make coccicheck that complains with the following warning:
drivers/input/touchscreen/cyttsp4_i2c.c:53:1-3: WARNING: PTR_ERR_OR_ZERO can be used
