From 7c2378800cf7ac87e2663afa7f39d102871f0c28 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 3 Dec 2019 11:20:37 +0100 Subject: firmware: dmi: Add dmi_memdev_handle Add a utility function dmi_memdev_handle() which returns the DMI handle associated with a given memory slot. This will allow kernel drivers to iterate over the memory slots.
