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)
Message-ID: <20191116110428.fI-5MoXqPxYfkvCU05aaRG5YJWUWQWAWmD_9wOOoh1Q@z> (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.
