--------------------------------

ACPICA commit cdf48b141d7da38e47fe4020310033ddd1971f9e

Writing a buffer to a PlatformRtMechanism FieldUnit invokes a
bidirectional transaction. The input buffer contains 26 bytes
containing 9 bytes of status, a command byte and a 16-byte UUID.
This change will will simply pass this incoming buffer to a handler
registered by the OS.
