Commitb2b32a1738("ACPI: bus: update acpi_dev_hid_uid_match() to support multiple types") added _UID matching support for both integer and string types, which satisfies NULL @uid2 argument for string types using inversion, but this logic prevents _UID comparision in case the argument is integer 0, which may result in false positives. Fix this using _Generic(), which will allow NULL @uid2 argument for string types as well as _UID matching for all possible integer values.
