From b018a8c71602d53d5d5ebac859f33327b97e9cec Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Mon, 6 Jul 2015 16:31:26 +0800 Subject: [PATCH] video: vesa_fb: Look up VGA device by class instead of id Per PCI spec, VGA device reports its class as standard 030000h in its configuration space, so we can use it to determine if we need run option rom instead of testing the supported vendor/device ids.
