The commit 78bcac7b2ae1e ("Input: add support for the STMicroelectronics FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper function in order to get the value of common properties. But, commit 78bcac7b2ae1e didn't set the capability of ABS_MT_POSITION_* before calling touchscreen_parse_properties(). In result, the max_x and max_y of 'struct touchscreen_properties' were not set.
