From 74c958a3766cd1948978a60cc995c17145a5eed8 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Tue, 19 Mar 2019 17:20:09 +0800 Subject: [PATCH] drm/amd/powerplay: optimization feature mask function for asic 1.change function return value type: from "unallowed" to "allowed" 2.replace feature mask number with feature macro, the code will clear.
