ACPI: don't duplicate input events on netlink
The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
