Just removed the hold on kmod (24-1ubuntu3) and updated to kmod (24-1ubuntu3.2). The touchpad is still working. Thanks for everyone's effort on this issue. Greatly appreciate it.

PNP LEN0049 will use smbus by default in kernel, but i2c bus is in runtime suspend mode in old touchpad fw. Then touchpad will not work. LEN2040 on 11e 3rd can reproduce this issue by passing psmouse.synaptics_intertouch=1 These 2 pnp device should be the same one Synaptics s3203_ver5. [Fix] i2c-i801 should auto suspend when not used, no need runtime pm. [Test Case] Tested on Thinkpad 11e 3rd. Touchpad works fine. [Regression Potential] Low, upstream fix cherry-picked. 4.18 kernel patch, no need for cosmic. Original bug report: ================= After upgrading to kmod (24-1ubuntu3.1) the trackpads stop working on Lenovo 11e 2nd gen machines. We have a fleet of approximetly 1000 of them in production running ubuntu 18.04. Prior to this update the trackpads worked out of box in 18.04. We are currently working around the issue by deploying our own blacklist files.
