Referring to another case #207759 (https://bugzilla.kernel.org/show_bug.cgi?id=207759)
I am curious why ideapad 15 has the same Touchpad ID and someone could solve the issue by blacklist elan-i2c but Legion 15ARH05 cannot, especially I didn't complied elan-i2c or elants-i2c. Legion 15ARH05 doesn't have touchscreen.
