From 4de2d58bc973caa8988b44ddd11787e57051c843 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 11 May 2016 20:57:44 +0200 Subject: [PATCH] clk: sunxi: tcon-ch1: Do not return a negative error in get_parent get_parent is supposed to return an unsigned 8 bit integer, so returning -EINVAL is a bad idea. Remove it.
