('PORT_HOTPLUG_EN', '0x61110', '0x180000')[1]
That happens here[2]:
} else if (IS_VALLEYVIEW(dev_priv)) {
/* ... */
seq_printf(m, "Port hotplug:\t%08x\n",
I915_READ(PORT_HOTPLUG_EN));
/* ... */
} else if (!HAS_PCH_SPLIT(dev_priv)) {
We don't take any extra wakerefs for VLV but on CHV we do:
intel_display_power_get(dev_priv, POWER_DOMAIN_INIT);
for this register and the following DP registers.
Keeping this as medium bacause:
1. user impact is negligible - it's an error in the debugfs
2. CI impact is medium - kernel taints and stops execution on this bug
