Subject: ACPI: acpi_pci_unbind should clean up properly after acpi_pci_bind
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=97719a8726fe8d3ea12a85fbf4f514a915ba30ec;p=deliverable%2Flinux.git

ACPI: acpi_pci_unbind should clean up properly after acpi_pci_bind

In acpi_pci_bind, we set device->ops.bind and device->ops.unbind, but
never clear them out.
