From 8cf0adf2f8c3f9f30ba4f1b79e051993aea158d7 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 24 Mar 2017 14:28:28 -0700 Subject: [PATCH] Input: synaptics-rmi4 - fix handling failures from rmi_enable_sensor If rmi_enable_sensor() fails in rmi_driver_probe(), we should not return immediately, but disable IRQs and tear down function list.
