Subject: [PATCH] PCI: aardvark: Make main irq_chip structure a 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.
|
|
|
|
We have already converted others irq_chip structures in this driver in
|
|
this way, but we omitted this one because the .name member is
|
|
dynamically created from device's name, and the name is displayed in
|
|
sysfs, so changing it would break sysfs ABI.
|
|
|
|
The rationale for changing the name (to "advk-INT") in spite of sysfs
|
|
ABI, and thus allowing to convert to a static structure, is that after
|
|
the other changes we made in this series, the IRQ chip is basically
|
|
something different: it no logner generates ERR and PME interrupts (they
|
|
are generated by emulated bridge's rp_irq_chip).
