Subject: [PATCH 4/5] drm/amd/display: Remove set but not used variable 'pixel_width'
Date: Sat, 5 Oct 2019 10:44:35 +0800	[thread overview]
Message-ID: <1570243476-44419-5-git-send-email-zhengbin13@huawei.com> (raw)
In-Reply-To: <1570243476-44419-1-git-send-email-zhengbin13-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

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

drivers/gpu/drm/amd/display/dc/dcn20/dcn20_dpp.c: In function dpp2_get_optimal_number_of_taps:
drivers/gpu/drm/amd/display/dc/dcn20/dcn20_dpp.c:359:11: warning: variable pixel_width set but not used [-Wunused-but-set-variable]

It is not used since commit f7de96ee8b5f ("drm/amd/display:
Add DCN2 DPP")
