3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Hung <alex.h...@canonical.com>
commit 63a78bb1051b240417daad3a3fa9c1bb10646dca upstream.
According to responses from the BIOS team, ASUS_WMI_METHODID_DSTS2
(0x53545344) will be used as future DSTS ID. In addition, calling
asus_wmi_evaluate_method(ASUS_WMI_METHODID_DSTS2, 0, 0, NULL) returns
ASUS_WMI_UNSUPPORTED_METHOD in new ASUS laptop PCs. This patch fixes
no DSTS ID will be assigned in this case.
