[PATCH v5 2/2] HID: logitech: Support WirelessDeviceStatus connect events
This patch allows WirelessDeviceStatus (0x1d4b) events to be detected as connection events in the hid-logitech-hidpp module. Devices with HIDPP_QUIRK_WIRELESS_DEVICE_STATUS use WirelessDeviceStatus instead of traditional connect events. Since all Bluetooth LE devices seem to act this way, HIDPP_QUIRK_CLASS_BLUETOOTH_LE aliases this quirk.
