From 51578b9b1f6a9299e36fcf1554ff8cdf79372bd3 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 23 Aug 2013 15:49:00 +0800 Subject: [PATCH] pinctrl: rockchip: Simplify pin_to_bank equation If (b->pin_base + b->nr_pins - 1) < pin is true, pin >= b->pin_base is always true because b->nr_pins is never less than 0. Thus this patch simplify the equation.
