Add two new callbacks,.setup() and .cleanup(), struct acpi_bus_type and modify acpi_platform_notify() to call .setup() after executing acpi_bind_one() successfully and acpi_platform_notify_remove() to call .cleanup() before running acpi_unbind_one(). This will allow the users of struct acpi_bus_type, PCI in particular, to specify operations to be executed right after the given device has been associated with a companion struct acpi_device and right before it's going to be detached from that companion, respectively. The main motivation is to be able to get rid of acpi_pci_bind() and acpi_pci_unbind(), which are horrible horrible stuff. [In short, there are three problems with them: The way they populate the .bind() and .unbind() callbacks of ACPI devices is rather less than straightforward, they require special hotplug-specific paths to be present in the ACPI namespace scanning code and by the time acpi_pci_unbind() is called the PCI device object in question may not exist any more.] Signed-off-by: Rafael J.
