If anyone has any objections, please let me know. ------------------ From: Jiri Kosina commit 3d88ba86ba6f35a0467f25a88c38aa5639190d04 upstream. This reverts commit 251efae73bd46b097deec4f9986d926813aed744. Quoting Wang Yuli: "The 27C6:01E0 touchpad doesn't require the workaround and applying it would actually break functionality. The initial report came from a BBS forum, but we suspect the information provided by the forum user may be incorrect which could happen sometimes. [1] Further investigation showed that the Lenovo Y9000P 2024 doesn't even use a Goodix touchpad. [2] For the broader issue of 27c6:01e0 being unusable on some devices, it just need to address it with a libinput quirk. In conclusion, we should revert this commit, which is the best solution."
