Implement remove() callback function for the Mediatek PCIe controller driver to add loadable kernel module support. Save the PCIe's GIC IRQ at probe so that it can be retrieved to call dispose_irq() to tear down the IRQ upon module removal.

|
Adds support for the Intel Volume Management Device (VMD). VMD is a
|
|
secondary PCI host bridge that allows PCI Express root ports,
|
|
and devices attached to them, to be removed from the default
|
|
PCI domain and placed within the VMD domain. This provides
|
|
more bus resources than are otherwise possible with a
|
|
single domain. If you know your system provides one of these and
|
|
has devices attached to it, say Y; if you are not sure, say N.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called vmd.
