From 6a20fdd606d7401aa6c7740af0927d56f15680ff Mon Sep 17 00:00:00 2001
From: Dan Carpenter <dan.carpenter@oracle.com>
Date: Mon, 4 Jan 2016 23:44:24 +0300
Subject: [PATCH 0142/1110] drm/amd/powerplay: precedence bug in
init_non_clock_fields()
The cast to uint8_t happens before the right shift so this always sets
.m3arb to zero. The cast is actually a no-op so we can remove it.
Fixes: 3bace3591493 ('drm/amd/powerplay: add hardware manager sub-component')
