Subject[PATCH 6/7] drm/amd/powerplay: remove set but not used variable 'state'
Date
Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/powerplay/smumgr/fiji_smumgr.c: In
function ‘fiji_populate_memory_timing_parameters’:
drivers/gpu/drm/amd/powerplay/smumgr/fiji_smumgr.c:1504:8:
warning: variable ‘state’ set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.

Fixes: 2e112b4ae3ba ("drm/amd/pp: remove fiji_smc/smumgr split.")
