From a09d0ba1745b607070a937083ecf9ec616178768 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 24 Jun 2016 14:00:27 +0100 Subject: [PATCH] drm/i915: Move module init/exit to i915_pci.c The module init/exit routines are a wrapper around the PCI device init/exit, so move them across. Note that in order to avoid exporting the driver struct, instead of manipulating driver.features inside i915_init we instead opt to simply exit if i915.modeset is disabled.
