Subject: [PATCH] mtd: maps: pci: balance PCI enable on cleanup
Date: Mon, 14 Sep 2026 21:06:47 -0400 [thread overview]
Message-ID: <20260915010647.54099-1-mhun512@gmail.com> (raw)
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.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
