Building DRM for i.MX fails with linux-next 20130212

[Fabio Estevam <festevam@xxxxxxxxx>]

Hi,

Building imx_v6_v7_defconfig on linux-next 20130212 gives me the
following build error:

  CC      drivers/gpu/drm/drm_pci.o
drivers/gpu/drm/drm_pci.c: In function ‘drm_pcie_get_speed_cap_mask’:
drivers/gpu/drm/drm_pci.c:485:2: error: implicit declaration of
function ‘pcie_capability_read_dword’
[-Werror=implicit-function-declaration]

Then I tried to fix it as follows:

diff --git a/drivers/gpu/drm/Makefile b/drivers/gpu/drm/Makefile

 drm-usb-y   := drm_usb.o

,which caused another issue:

Any ideas or suggestions?

Thanks,
