[PATCH] mtd: maps: pci: balance PCI enable on cleanup

[PATCH] mtd: maps: pci: balance PCI enable on cleanup

[Myeonghun Pak]

mtd_pci_probe() leaves the PCI device enabled on later probe failure and
mtd_pci_remove() does not disable it either. Use pcim_enable_device() to
release the enable reference after the existing map and region cleanup.

The imbalance is already present in the initial Git import.

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