2018-10-20HID: quirks: fix support for Apple Magic KeyboardsNatanael Copa
Commit b6cc0ba2cbf4 (HID: add support for Apple Magic Keyboards) backported support for the Magic Keyboard over Bluetooth, but did not add the BT_VENDOR_ID_APPLE to hid_have_special_driver[] so the hid-apple driver is never loaded and Fn key does not work at all. Adding BT_VENDOR_ID_APPLE to hid_have_special_driver[] is not needed after commit e04a0442d33b (HID: core: remove the absolute need of hid_have_special_driver[]), so 4.16 kernels and newer does not need it.

2018-02-17HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not workingHans de Goede
commit edfc3722cfef4217c7fe92b272cbe0288ba1ff57 upstream. The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo (single i2c_hid device for both) which has a vid:pid of 04F3:0401, which is also used by a bunch of Elan touchpads which are handled by the drivers/input/mouse/elan_i2c driver, but that driver deals with pure touchpads and does not work for a combo device such as the one on the Toshiba Click Mini. The combo on the Mini has an ACPI id of ELAN0800, which is not claimed by the elan_i2c driver, so check for that and if it is found do not ignore the device. This fixes the keyboard/touchpad combo on the Mini not working (although with the touchpad in mouse emulation mode).
