[PULL 05/86] acpi/nvdimm: define macro for NVDIMM Device _DSM

Posted by Michael S. Tsirkin 3 years, 3 months ago

From: Robert Hoo <robert.hu@linux.intel.com>

Since it will be heavily used in next patch, define macro
NVDIMM_DEVICE_DSM_UUID for "4309AC30-0D11-11E4-9191-0800200C9A66", which is
NVDIMM device specific method uuid defined in NVDIMM _DSM interface spec,
Section 3. [1]

No functional changes in this patch.
