Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ARM: footbridge: fix PCI interrupt mapping<br /> <br /> Since commit 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in<br /> pci_device_probe()"), the PCI code will call the IRQ mapping function<br /> whenever a PCI driver is probed. If these are marked as __init, this<br /> causes an oops if a PCI driver is loaded or bound after the kernel has<br /> initialised.
