Bug Description
The kernel driver elan_i2c_core.c is missing the elan_acpi_id for the touchpad used in the Lenovo V130-14IGM laptop. The elan_acpi_id for the touchpad used in the Lenovo V130-14IGM is ELAN0615.
I got the touchpad working by building my own patched kernel with "{ "ELAN0615", 0 }," added in drivers/
Though the touchpad is working properly since using the custom kernel, I get masses of the following kernel errors:
[ xxx.xxx ] elan_i2c i2c-ELAN0615:01: invalid report id data (ff)
System:
Lenovo V130-14IGM
Software:
Ubuntu 18.04.1 x64 with standard kernel doesn't recognize the touchpad. With my custom kernel (currently Ubuntu mainline kernel v4.18-rc8) it is working with the mentioned kernel errors.
Can someone please commit the mentioned elan_acpi_id in the kernel?
Thanks!

I have a brand new Lenovo 130-15IKB and have discovered the touchpad is ELAN0620:01. Seems like this whole line of touchpads needs to have support added in the kernel.
