From 5a8a6b89c15766446d845671d574a9243b6d8786 Mon Sep 17 00:00:00 2001 From: Jingkui Wang Date: Mon, 12 Dec 2016 13:51:46 -0800 Subject: [PATCH] Input: drv260x - fix input device's parent assignment We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.
