+Subject: [PATCH 4412/4736] drm/amd/powerplay: remove set but not used variable
+ 'data'
+
+Fixes gcc '-Wunused-but-set-variable' warning:
+
+drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c: In function vega10_get_performance_level:
+drivers/gpu/drm/amd/powerplay/hwmgr/vega10_hwmgr.c:5217:23: warning: variable data set but not used [-Wunused-but-set-variable]
+
+'data' is introduced by commit f688b614b643 ("drm/amd/pp:
+Implement get_performance_level for legacy dgpu"), but never used,
+so remove it.
