Subject: [PATCH] PCI: aardvark: Make MSI irq_chip structures static driver

Marc Zyngier says [1] that we should use struct irq_chip as a global
|
|
static struct in the driver. Even though the structure currently
|
|
contains a dynamic member (parent_device), Marc says [2] that he plans
|
|
to kill it and make the structure completely static.
|
|
|
|
Convert Aardvark's priv->msi_bottom_irq_chip and priv->msi_irq_chip to
|
|
static driver structure.
