Subject: [PATCH 6/7] drm/amd/powerplay: remove set but not used variable 'state'
Date: Wed, 13 Nov 2019 20:44:33 +0800 [thread overview]
Message-ID: <1573649074-72589-7-git-send-email-yukuai3@huawei.com> (raw)
In-Reply-To: <1573649074-72589-1-git-send-email-yukuai3@huawei.com>
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.")
