[PATCH 28/42] PCI: aardvark: Free config space for emulated root bridge when unbinding driver to fix memory leak
From: Pali Rohár <pali@kernel.org>
Date: 2021-05-06 15:36:31
Also in:
linux-pci, lkml
Subsystem:
pci driver for aardvark (marvell armada 3700), pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers:
Thomas Petazzoni, Pali Rohár, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds
Do it after disabling and masking all interrupts, since aardvark interrupt
handler accesses config space of emulated root bridge.
