X-Git-Tag: v4.17~20^2~3 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=15e2cffec3aa0d47a8d75ae80e1b136bfb5dff30;p=uclinux-h8%2Flinux.git Input: synaptics - Lenovo Thinkpad X1 Carbon G5 (2017) with Elantech trackpoints should use RMI Lenovo use two different trackpoints in the fifth generation Thinkpad X1 Carbon. Both are accessible over SMBUS/RMI but the pnpIDs are missing. This patch is for the Elantech trackpoint specifically which also reports SMB version 3 so rmi_smbus needs to be updated in order to handle it. For the record, I was not the first one to come up with this patch as it has been floating around the internet for a while now. However, I have spent significant time with testing and my efforts to find the original author of the patch have been unsuccessful.
