This needs to be applied on top of:

Raydium touchscreen on ThinkPad L390 doesn't work.

Use I2C_HID_QUIRK_NO_IRQ_AFTER_RESET to introduce an extra delay after
resetting the device.

User confirmed the touchpad works with the patch.

[Regression Potential]
Low. This fix limits to one device and is quite trivial.
