The recently added PTN3460 device driver uses interfaces that are provided by the KMS helper infrastructure, so we should explicitly select that to avoid this linker error:

ERROR: "drm_helper_probe_single_connector_modes" [drivers/gpu/drm/bridge/ptn3460.ko] undefined! ERROR: "drm_helper_connector_dpms" [drivers/gpu/drm/bridge/ptn3460.ko] undefined!

Ah, right. Exynos drm selects DRM_KMS_HELPER so I cannot see build error.

Thanks, Inki Dae

We have to drop the I2C dependency to avoid a circular dependency chain, but that's ok because DRM already selects I2C.

I found this today doing randconfig builds on linux-next.
