Series HID: multitouch: Disable event reporting on suspend when the device is not a wakeup-source | expand

Commit Message

Hans de Goede May 29, 2021, 3:14 p.m. UTC 
Without a ll-driver callback hid_hw_may_wakeup() will return:
device_may_wakeup(hdev->dev.parent), but for the hid devices
instantiated by logitech-dj for devices behind the receiver the
logitech-dj hid(pp)-device is the parent.

Add a logi_dj_ll_may_wakeup() callback which calls hid_hw_may_wakeup()
on the logitech-dj hid(pp) parent-hid-device.
