[ Upstream commit a7adabeece570b8a566dd592219410456676796e ]
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.
