ACPI / dock / PCI: Drop ACPI dock notifier chain
The only user of the ACPI dock notifier chain is the ACPI-based PCI hotplug (acpiphp) driver that uses it to carry out post-dock fixups needed by some systems with broken _DCK. However, it is not necessary to use a separate notifier chain for that, as it can be simply replaced with a new callback in struct acpi_dock_ops. For this reason, add a new .fixup() callback to struct acpi_dock_ops and make hotplug_dock_devices() execute it for all dock devices with hotplug operations registered. Accordingly, make acpiphp point that callback to the function carrying out the post-dock fixups and do not register a separate dock notifier for each device registering dock operations. Finally, drop the ACPI dock notifier chain that has no more users. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
