Subject: drm/i915/display: Mark conn as initialised by iterator
Git-commit: f9d9fece29b8b5cd4943eccd7bd73b6241d424fa
Patch-mainline: v5.5-rc1
References: bsc#1152489

smatch complains about
drivers/gpu/drm/i915//display/intel_display.c:14403 intel_set_dp_tp_ctl_normal() error: uninitialized symbol 'conn'.
because it has no way to determine that the loop must have an entry.
Tell the static analysers to ignore the local, it will always be set.
