Input: synaptics-rmi4 - limit the range of what GPIOs are buttons By convention the first 6 bits of F30 Ctrl 2 and 3 are used to signify GPIOs which are connected to buttons. Additional GPIOs may be used as input GPIOs to signal the touch controller of some event (ie disable touchpad). These additional GPIOs may meet the criteria of a button in rmi_f30_is_valid_button() but should not be considered buttons. This patch limits the GPIOs which are mapped to buttons to just the first 6.
