From 2cd82d06e4c62f927ede33e62f9f0507d64903c9 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 22 Feb 2016 11:14:25 -0800 Subject: [PATCH] simplefb: Remove impossible check for of_clk_get_parent_count() < 0 The check for < 0 is impossible now that of_clk_get_parent_count() returns an unsigned int. Simplify the code and update the types.
