[PATCH] regulator, mc13xxx: Remove pointless test for unsigned lessthan zero

From: Jesper Juhl
Date: Wed Feb 23 2011 - 17:46:49 EST


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.
