Subject: [PATCH] drm/gma500: remove set but not used variable 'channel_eq'
Date: Sat, 16 Nov 2019 19:04:28 +0800	[thread overview]
Message-ID: <1573902268-117518-1-git-send-email-zhengbin13@huawei.com> (raw)

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

drivers/gpu/drm/gma500/cdv_intel_dp.c: In function cdv_intel_dp_complete_link_train:
drivers/gpu/drm/gma500/cdv_intel_dp.c:1596:7: warning: variable channel_eq set but not used [-Wunused-but-set-variable]

It is never used, so remove it.
