[PULL v2 28/30] acpi: cpuhp: document CPHP_GET_CPU_ID_CMD command

Posted by Michael S. Tsirkin 5 years, 8 months ago

From: Igor Mammedov <imammedo@redhat.com>

Commit 3a61c8db9d25 introduced CPHP_GET_CPU_ID_CMD command but
did not sufficiently describe it. Fix it by adding missing command
documentation.
