I want to propose to backport commit e4c9062717fe ("Input: elantech - fix protocol errors for some trackpoints in SMBus mode") to the active stable kernels. This commit repairs the track point and the touch pad buttons on a Lenovo Thinkpad E15 here. Without this change I don't get any events apart from an error message for each button press or move of the track point in the kernel log. (Also the error message is the same for all buttons and the track point, so I cannot create a new input event driver in userspace that emulates the right event depending on the error message :-) At least to 5.10.x it applies cleanly, I didn't try the older stable branches.
