While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed' warning. Because lenovo_ymc_probe() calls lenovo_ymc_notify() and that time the YMC part is not triggered yet (which is mandatory for this model). At the end of lenovo_ymc_notify() YMC is triggered by the ideapad-laptop driver and then lenovo_ymc_notify() will be called by WMI to report the actual value. Add 0x0 YMC state to the sparse keymap to ignore.
