From 037e966f2d63896129220112644f32962af6d115 Mon Sep 17 00:00:00 2001 From: Hartmut Knaack Date: Thu, 9 Jul 2015 23:51:29 +0200 Subject: iio:light:stk3310: move device register to end of probe iio_device_register should be the last operation during probe. Therefor move up interrupt setup code and while at it, change the check for invalid values of client->irq to be smaller than zero. Fixes: 3dd477acbdd1 ("iio: light: Add threshold interrupt support for STK3310") As the device_register makes the userspace interfaces of the device available it is possible for requests to come in before the probe sequence has finished. This can lead to unhandled interrupts and similar.
