From bd580e7ed4add8ce9b2c1dd1911f8fb9d444128b Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Sat, 2 May 2015 17:03:24 +0200 Subject: clocksource: integrator: Fix of_io_request_and_map error check of_io_request_and map returns an error pointer, but the current code assumes that on error the returned pointer will be NULL. Obviously, that makes the check completely useless. Change the test to actually check for the proper error code.
