+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')
