Subject: [PATCH 05/26] Input: synaptics-rmi4 - call rmi_driver_process_config_requests in enable_sensor

From: Benjamin Tissoires <benjamin.tissoires@...hat.com>

The SMBus devices have their IRQs disabled after a reset. We need to
configure them by calling rmi_driver_process_config_request() when
enabling the sensor.
