--- Comment #11 from Dexuan Cui (de...@microsoft.com) ---
This is my v1 fix: https://lkml.org/lkml/2020/12/18/514

Yesterday Rafael J. Wysock sugested that I should make a new fix using
kstrdup_const(): https://lkml.org/lkml/2021/1/8/48

So I posted v2 later yesterday: https://lkml.org/lkml/2021/1/8/53

So far, no comment yet. Let me ping the ACPI maintainers now since we know more
people are being affected.
