From 4b2f67d756cf4a5ed8e8d11caa7dcea06c41a09e Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Wed, 23 Feb 2011 23:45:55 +0100 Subject: regulator, mc13xxx: Remove pointless test for unsigned less than zero The variable 'val' is a 'unsigned int', so it can never be less than zero. This fact makes the "val < 0" part of the test done in BUG_ON() in mc13xxx_regulator_get_voltage() rather pointles since it can never have any effect. This patch removes the pointless test.
