HID: logitech-hidpp: Add hidpp_non_unifying_init() helper
Turn hidpp_overwrite_name() into a hidpp_non_unifying_init() helper which takes care of setting both the name and the serial for non unifying devices. This mirrors the hidpp_unifying_init() helper for unifying devices. This series has been tested on the following devices: Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0) Logitech M720 Triathlon (bluetooth, HID++ 4.5) Logitech M720 Triathlon (unifying, HID++ 4.5) Logitech K400 Pro (unifying, HID++ 4.1) Logitech K270 (eQUAD nano Lite, HID++ 2.0) Logitech M185 (eQUAD nano Lite, HID++ 4.5) Logitech LX501 keyboard (27 Mhz, HID++ builtin scroll-wheel, HID++ 1.0) Logitech M-RAZ105 mouse (27 Mhz, HID++ extra mouse buttons, HID++ 1.0) And by bentiss: Logitech Touchpad T650 (unifying) Logitech Touchpad T651 (bluetooth) Logitech MX Master 3B (BLE) Logitech G403 (plain USB / Gaming receiver) Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20231010102029.111003-8-hdegoede@redhat.com Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>
