From 616bf80d381da13fbb392ebff06f46f946e3ee84 Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Fri, 13 Jul 2018 12:27:26 +0200 Subject: [PATCH] clk: mvebu: armada-37xx-periph: Fix wrong return value in get_parent The return value of the get_parent operation is a u8, whereas a -EINVAL was returned. This wrong value was return if the value was bigger that the number of parent but this case was already handled by the core. So we can just remove this chunk of code to fix the issue.
