Subject: drm/amd/display: Remove unused variables from dcn10_stream_encoder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 54c3e9493cd502d63ff3643fa70b5f98b3201846
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The variable regval from the function enc1_update_generic_info_packet
and the variables dynamic_range_rgb and dynamic_range_ycbcr from the
function enc1_stream_encoder_dp_set_stream_attribute are not currently
used.
This was pointed by clang with the following warnings:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_stream_encoder.c:62:11:
warning: variable 'regval' set but not used [-Wunused-but-set-variable]
uint32_t regval;
