Subject: HID: logitech-hidpp: add HIDPP_QUIRK_DELAYED_INIT for the T651.
From: Mike Hommey <mh@xxxxxxxxxxxx>
commit 5fe251112646d8626818ea90f7af325bab243efa upstream.
commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication if
not necessary") put restarting communication behind that flag, and this
was apparently necessary on the T651, but the flag was not set for it.
Fixes: 498ba2069035 ("HID: logitech-hidpp: Don't restart communication if not necessary")
