From 7c9574f262a25c7ca0779df31098ba4e0c382e86 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 4 Jan 2016 23:44:24 +0300 Subject: [PATCH] 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.
