Subject: drm/amd/display: remove set but not used variable 'pixel_width'
MIME-Version: 1.0

Git-commit: 509c58189c8d695ef9cd12093a22ddbd6cdb8d71
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

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

drivers/gpu/drm/amd/display/dc/dcn10/dcn10_dpp.c:137:11: warning: variable ‘pixel_width’ set but not used [-Wunused-but-set-variable]

It is introduced by commit 70ccab604049 ("drm/amdgpu/display:
Add core dc support for DCN"), but never used, so remove it.
