Bug Description

I tried 3 times to open a bug always receive a messages saying an error occurred processing my email:

error ID OOPS-d51b412e09e6c644761848bc29812cb2
error ID OOPS-68981770c2bf09243ce2f2fd286b161e
error ID OOPS-b3c2882e126b0cf5c60dde5cc9fecd0b

The last attempt to file the bug had the following body:

I have just bought a new laptop from Teclast model F6 Pro. I have installed Ubuntu LTS 18.04.2 (kernel 4.18.0-16-generic).

The Goodix touchpad of the laptop is not recognized by the kernel version used by Ubuntu LTS 18.04.2.

That is my kernel error:

[ 3.733842] i2c_hid i2c-SYNA3602:00: i2c-SYNA3602:00 supply vdd not found, using dummy regulator
[ 3.738296] i2c_hid i2c-SYNA3602:00: unexpected HID descriptor bcdVersion (0x0000)

The problem is known, it is described here:

A patch is available here:

It looks like that patch entered in the mainline kernel since 4.20 (or 4.19 I am not sure).

It would be very helpful if that patch is added to Ubuntu 18.04.2 LTS 4.18.0-16-generic kernel to help the users of Teclast laptops like me.

On several Teclast laptops the touchpad is not supported on Unbuntu 18.04.2 (for sure F6 pro and F7).

Presumably needs a fix similar to r18904, or preferably something more global.
