+Subject: [PATCH 4425/4736] drm/amd/display: remove set but not used variable
+ 'bpc'
+
+Fixes gcc '-Wunused-but-set-variable' warning:
+
+drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c: In function get_pbn_from_timing:
+drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:2364:11: warning:
+ variable bpc set but not used [-Wunused-but-set-variable]
+
+It is not used since commit e49f69363adf ("drm/amd/display: use
+proper formula to calculate bandwidth from timing"), this also
+remove get_color_depth(), which is only used here.
