+Subject: [PATCH 1714/2940] drm/amdgpu: remove unnecessary rlc reset function
+ on gfx9
+
+The rlc reset function is not necessary during gfx9 initialization/resume phase.
+And this function would even cause rlc fw loading failed on some gfx9 ASIC.
+Remove this function safely with verification well on Vega/Raven platform.
