    Subject[PATCH 4.4 106/143] ARM: iop32x/n2100: fix PCI IRQ mapping
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Russell King <rmk+kernel@armlinux.org.uk>

    commit db4090920ba2d61a5827a23e441447926a02ffee upstream.

    Booting 4.20 on a TheCUS N2100 results in a kernel oops while probing
    PCI, due to n2100_pci_map_irq() having been discarded during boot.
