Hi Aka, as attached in issue crosbug.com/p/58950#21, the .*.auto is common to all platform device, not just audio codec.

https://cs.corp.google.com/chromeos_public/src/third_party/kernel/v4.4/drivers/base/platform.c?type=cs&q=drivers/base/platform+package:%5Echromeos_public$&l=338


I changed the subject to reflect the fact.
Thanks!

This should be a quick fix, right

gooftool: Remove ".*.auto" suffix in probe result.

When the platform add the device, it would add the .*.auto suffix to the
device name. It causes the probe module gets the different value form the
samecomponent. Therefore we remove the auto-generated suffix.
