Subject: [PATCH AUTOSEL 4.9 043/141] drm/radeon: remove set but not used variable 'backbias_response_time'
Date: Fri, 14 Feb 2020 11:19:43 -0500
Message-ID: <20200214162122.19794-43-sashal@kernel.org> (raw)
In-Reply-To: <20200214162122.19794-1-sashal@kernel.org>

From: zhengbin <zhengbin13@huawei.com>

[ Upstream commit ac52caecbcf2c30ce95b2536c1caf2643c49b91c ]

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

drivers/gpu/drm/radeon/si_dpm.c: In function si_program_response_times:
drivers/gpu/drm/radeon/si_dpm.c:3640:29: warning: variable backbias_response_time set but not used [-Wunused-but-set-variable]

It is introduced by commit a9e61410921b ("drm/radeon/kms:
add dpm support for SI (v7)"), but never used, so remove it.
