+Subject: [PATCH 4597/4736] drm/amd/powerplay: remove set but not used variable
+ 'stretch_amount2'
+
+drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/vegam_smumgr.c:
+ In function vegam_populate_clock_stretcher_data_table:
+drivers/gpu/drm/amd/amdgpu/../powerplay/smumgr/vegam_smumgr.c:1489:29:
+ warning: variable stretch_amount2 set but not used [-Wunused-but-set-variable]
+
+It is never used, so can be removed.
