From 5b8e5363faa19f6f5064df7f3830c7b56d80f28d Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Mon, 9 Dec 2019 14:08:59 +0100 Subject: acpi: cpuhp: spec: clarify store into 'Command data' when 'Command field' == 0 Write section of 'Command data' register should describe what happens when it's written into. Correct description in case the last stored 'Command field' value is equal to 0, to reflect that currently it's not supported.
