linux-next: build warning after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from drivers/gpu/drm/drm_pci.c:29:0:
include/drm/drm_pci.h:76:64: warning: 'struct platform_device' declared inside parameter list
 extern int drm_platform_init(struct drm_driver *driver, struct platform_device *platform_device);
                                                                ^
include/drm/drm_pci.h:76:64: warning: its scope is only this definition or declaration, which is probably not what you want

Introduced by commit

  23ef59ef6dcc ("drm: Extract drm_pci.h")

A forgotten include file (or maybe just a forward declaration of the struct).
