From e4cf19ffe060e75d34c007565d0aef7189ec654e Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Tue, 2 Sep 2014 15:50:43 -0400 Subject: [PATCH] HID: thingm: set the proper error code before leaving In case of an unsupported firmware, the driver bails out without setting the LEDs interfaces, but forget to set the proper error code. err is then still equal to 0 and the hid subsytem consider the device to be in perfect shape. When removing it, thingm_remove() tries to unbind the rgb LEDs which has not been created, leading to a segfault.
