commit 15dcbce5cf5d06111d9f7e4a040e13b21fb228cf

jetway/nf81-t56n-lf: Serialize ACPI methods to avoid races.

Fix the remark introduced in ACPICA version 20130517 that gives the
    following explanation:

If a thread blocks within the method for any reason, and another thread
       enters the method, the method will fail because an attempt will be
       made to create the same (named) object twice.

In this case, issue a remark that the method should be marked
       serialized. ACPICA BZ 909.
