Resolve keyboard not working out of the box for Dell XPS 9345 13" codenamed 'tributo'. X1E80100-based laptop's initial support is currently being upstreamed [1]. In present state, keyboard is succesfully initialized, however attempt to type anything throws 'incomplete report' errors. When utilizing I2C_HID_QUIRK_BAD_INPUT_SIZE quirk the error is gone, however raw data coming from the keyboard is always the same, no matter the key pressed. Issue 'resolves' itself when suspending and resuming the device. It appears that calling power on command one more time after device initialization before finishing off the probing fixes this weird behavior, and keyboard works right away. Introduce a new quirk for such behaviour, and enable it for particular keyboard. Vendor is shown as 'QTEC', however device id is reported as 0000. Given that vendor was not present before, using HID_ANY_ID to match the device should be okay in this case.
