6.11-stable review patch. If anyone has any objections, please let me know. ------------------ From: Gergo Koteles <soyer@xxxxxx> [ Upstream commit d9dca215708d32e7f88ac0591fbb187cbf368adb ] While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed' warning. This is caused by lenovo_ymc_probe() calling lenovo_ymc_notify() at probe time to get the initial tablet-mode-switch state and the key-code lenovo_ymc_notify() reads from the firmware is not initialized at probe time yet on the Lenovo 14ARB7. The hardware/firmware does an ACPI notify on the WMI device itself when it initializes the tablet-mode-switch state later on. Add 0x0 YMC state to the sparse keymap to silence the warning.
