arm:allmodconfig fails to build with several undefined drm and host1x symbols. drivers/gpu/drm/tegra/bus.c:52: undefined reference to `drm_dev_alloc' drivers/gpu/drm/tegra/bus.c:56: undefined reference to `drm_dev_register' drivers/gpu/drm/tegra/bus.c:67: undefined reference to `drm_dev_free' drivers/gpu/drm/tegra/bus.c:75: undefined reference to `drm_put_dev' drivers/gpu/drm/tegra/drm.c:445: undefined reference to `host1x_syncpt_get_base' drivers/gpu/drm/tegra/drm.c:449: undefined reference to `host1x_syncpt_base_id' and so on. This is caused by DRM=m but DRM_TEGRA=y. DRM_TEGRA is bool while DRM is tristate. DRM_TEGRA can not be set to tristate because it depends on unexported host1x symbols (and possibly others). Fix by updating DRM_TEGRA dependency. Also, the DRM_TEGRA help text states that it can be built as module. Remove that text since it is not (or no longer) correct.
