I recently bought a new laptop (Lenovo ideapad 530S-14ARR). While testing the 5.x series (now currently using the latest 5.1 RC) I had 1 main issue - my touchpad doesn't work. With the 4.18 it works fine.
If I run "cat /proc/bus/input/devices > ~/devices" on the 4.18 kernel, I see the following:
I: Bus=0018 Vendor=06cb Product=7f27 Version=0100
N: Name="MSFT0001:00 06CB:7F27 Touchpad"
P: Phys=i2c-MSFT0001:00
S: Sysfs=/devices/platform/AMDI0011:01/i2c-2/i2c-MSFT0001:00/0018:06CB:7F27.0003/input/input16

B: EV=1b
B: KEY=e520 10000 0 0 0 0
B: ABS=260800000000003
B: MSC=20
But when i run the same command in 5.x, it doesn't appear at all. Does anyone have clue how to resolve it?
