Subject: [PATCH 5/9] ACPI / dock: Add .uevent() callback to struct acpi_hotplug_context
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
In order to avoid the need to register special ACPI dock
operations for SATA devices add a .uevent() callback pointer to
struct acpi_hotplug_context and make dock_hotplug_event() use that
callback if available. Also rename the existing .event() callback
in struct acpi_hotplug_context to .notify() to avoid possible
confusion in the future.
