        <pre>Someone should test this:

+++ b/drivers/gpu/drm/i915/display/intel_display_power.c
@@ -423,10 +423,8 @@ icl_combo_phy_aux_power_well_enable(struct
drm_i915_private *dev_priv,
        val = I915_READ(regs->driver);
        I915_WRITE(regs->driver, val | HSW_PWR_WELL_CTL_REQ(pw_idx));

-       if (INTEL_GEN(dev_priv) < 12) {

Another observation I made was that the 1178 anaovrd w/a is no longer listed
for tgl, so should be nuked. Although it shouldn't matter for this particular
bug.</pre>
