From: Hans de Goede <redacted> [ Upstream commit 1e189f267015a098bdcb82cc652d13fbf2203fa0 ] Add a HID_QUIRK_NO_INIT_REPORTS quirk for the Dell K12A keyboard-dock, which can be used with various Dell Venue 11 models. Without this quirk the keyboard/touchpad combo works fine when connected at boot, but when hotplugged 9 out of 10 times it will not work properly. Adding the quirk fixes this.
