From 269fe32d3343b7b9e48ba533887f58eb877581c8 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 1 Nov 2017 03:56:19 +1000 Subject: [PATCH] drm/nouveau/bar: swap oneinit/init ordering, and rename bar3 to bar2 NVIDIA call it BAR2, Linux APIs treat it as BAR3 due to BAR1 being a 64-bit BAR, which I presume take two slots or something. No actual code changes here, just to make future commits less messy.
