    Subject[PATCH AUTOSEL 5.5 150/542] drm/amd/powerplay: remove set but not used variable 'us_mvdd'
    Date
    From: yu kuai <yukuai3@huawei.com>

    [ Upstream commit 472b36a2ab67880e89d6b0cd0e243830e8cb75e1 ]

    Fixes gcc '-Wunused-but-set-variable' warning:

    drivers/gpu/drm/amd/powerplay/smumgr/vegam_smumgr.c: In
    function ‘vegam_populate_smc_acpi_level’:
    drivers/gpu/drm/amd/powerplay/smumgr/vegam_smumgr.c:1117:11:
    warning: variable 'us_mvdd' set but not used [-Wunused-but-set-variable]

    It is never used, so can be removed.

    Fixes: ac7822b0026f ("drm/amd/powerplay: add smumgr support for VEGAM (v2)")
