Wysocki 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. Signed-off-by: Rafael J.
