Bug Description
== SRU Justification ==
[Impact]
Touchpad on sereval Lenovo ThinkBook doesn't work.
[Fix]
Maintain method calling ordering by calling _REG before issuing _STA, as
ACPI spec suggested, for I2C ACPI devices.
[Test]
Positive feedback from several users.
[Regression Potential]
If there are some systems that rely on the wrong calling ordering then
there's a regression risk. However it's rather unlikely.
== Original Bug Report ==
This is happening on a ThinkBook 14 IML 20RV.
