From c61872c9833d17d3807fb999096917c1f9eaada0 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Wed, 17 May 2017 13:25:12 +0300 Subject: [PATCH] firmware: dmi: Add DMI_PRODUCT_FAMILY identification string Sometimes it is more convenient to be able to match a whole family of products, like in case of bunch of Chromebooks based on Intel_Strago to apply a driver quirk instead of quirking each machine one-by-one. This adds support for DMI_PRODUCT_FAMILY identification string and also exports it to the userspace through sysfs attribute just like the existing ones.
