If anyone has any objections, please let me know. ------------------ From: Zhefu Zhang commit 3a046db33bb9f28b43a951a7a090db771dc0f8b3 upstream. The internal keyboard of the Xiaomi Book Pro 14 does not work unless atkbd skips deactivating it at the end of atkbd_probe(). Using 'i8042.dumbkbd=1' also makes the keyboard work, but then the driver never writes to the keyboard at all, so the Caps Lock LED is lost. The atkbd_deactivate_fixup quirk fixes both without a boot parameter.
