From bdacd1b426db83ac8ecf21aef1848120ffe53c07 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 11 Oct 2016 13:41:03 -0500 Subject: [PATCH] driver core: fix smatch warning on dev->bus check Commit d42a09802174 (driver core: skip removal test for non-removable drivers) introduced a smatch warning: drivers/base/dd.c:386 really_probe() warn: variable dereferenced before check 'dev->bus' (see line 373) Fix the warning by removing the dev->bus NULL check. dev->bus will never be NULL, so the check was unnecessary.
