After libinput received "SW_TABLET_MODE", then it will disable the keyboard and touchpad. [Test case] Test 200 times reboot with: 1. 5.10.0-1013-oem kernel: - the SW_TABLET_MODE was detected at 72 round and the keyboard / touchpad not work. 2. 5.10.0-1013-oem kernel + 67fbe02a5cebc3c653610f12e3c0424e58450153: - the SW_TABLET_MODE is not be detected within 200 times reboot. [Fix] Cherry-pick commit 67fbe02a5cebc3c653610f12e3c0424e58450153. It turns the tablet mode detection to off as default and could be enabled by module parameter "enable_tablet_mode_sw". [Regression potential] It will break tablet detection on all HP laptops but user can enable it back by adding module parameter. If without this patch then a lot of HP new laptops (with newer HP BIOS) will get the keyboard/touchpad not work after reboot.
