+Subject: HID: magicmouse: avoid setting up battery timer when not needed
+
+From: Aditya Garg <gargaditya08@live.com>
+
+commit 9bdc30e35cbc1aa78ccf01040354209f1e11ca22 upstream.
+
+Currently, the battery timer is set up for all devices using
+hid-magicmouse, irrespective of whether they actually need it or not.
+
+The current implementation requires the battery timer for Magic Mouse 2
+and Magic Trackpad 2 when connected via USB only. Add checks to ensure
+that the battery timer is only set up when they are connected via USB.
+
+Fixes: 0b91b4e4dae6 ("HID: magicmouse: Report battery level over USB")
