Subject: [PATCH] Input: elantech - add LEN2146 to SMBus blacklist for ThinkPad L13 Gen2
Date: Mon, 8 Feb 2021 10:52:03 +0300 [thread overview]
Message-ID: <20210208075205.3784059-1-nickel@altlinux.org> (raw)
ThinkPad L13 Gen2 has both touchpad and trackpoint.
PNP: LEN2146 PNP0f13
With the default protocol (elantech-smbus) trackpoint is not operating,
while touchpad does. Changing to elantech renders both operational.
