** Description changed:
+ === SRU Justification ===
+
+ [Impact]
+ AMD MP2 I2C driver doesn't support more than one bus.
+ This makes touchpad on Lenovo Yoga 530 doensn't work as expected.
+
+ [Fix]
+ Sync the MP2 driver with upstream version.
+
+ [Test]
+ The new upstream driver doesn't break on Latitude 5495.
+ Users haven't given any feedback yet, but since Disco is freezing I
+ am sending this out.
+
+ [Regression Potential]
+ Low. It's from upstream, and only a subset of Raven Ridge has this
+ device.
+
+ === Original Bug Report ===
+
The touchpad is not working and does not show up in cat
/proc/bus/input/devices on multiple kernels. I've tried the newest
kernel to date (19.08.18) and a few others.
The touchpad works on windows.
