From b6c40b8581d5f2c88d18d7905b9ff6ba9956f506 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Sun, 19 Feb 2012 13:10:00 +1100 Subject: w1_bq27000: remove unnecessary NULL test. As recent change means that we now dereference 'dev' before testing for NULL. That means either the change was wrong, or the test isn't needed. As this function is only called from one driver (bq27x000_battery) and it always passed a non-NULL dev, it seems good to assume that the test isn't needed. So remove it.
