From 8c1b1e54faed690261752afcba27c79ce4d3fa10 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 19 Feb 2016 17:29:17 -0800 Subject: [PATCH] clk: at91: Remove impossible checks for of_clk_get_parent_count() These checks for < 0 are impossible now that of_clk_get_parent_count() returns an unsigned int. Change the checks for == 0 and update the type.
