From 06e6ff8f10513ae863adeddf21510c99171a6283 Mon Sep 17 00:00:00 2001 From: Arun Siluvery Date: Thu, 28 Jan 2016 17:18:41 +0000 Subject: [PATCH] drm/i915: Capture PCI revision and subsytem details in error state Revision id along with device id is useful in better identification of the HW and its limitations so include this detail in error state. v2: make it clear that it is PCI revision and We might as well dump PCI subsystem details while we update this (Ville, Chris).
