[PATCH] parport: pc: balance PCI enable on cleanup

From: Myeonghun Pak

Date: Mon Sep 14 2026 - 21:07:59 EST


The PCI card probe enables the device without disabling it on later
failure or removal. Use pcim_enable_device() to release the enable
reference after the registered ports have been torn down.

The early return for already-probed onboard Super-I/O devices remains
unchanged and does not acquire a managed enable reference.

The imbalance is already present in the initial Git import.

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
