I'm getting compile errors:
drivers/staging/media/tegra-video/vi.c:1064:1: warning: data definition has no type or storage class
1064 | MODULE_DEVICE_TABLE(of, tegra_vi_of_id_table);

I'm applying the patches on top of the latest media_tree master.
It appears to be a missing module.h include in vi.c and csi.c.
If that's all it is, then just post a follow-up patch and I'll squash it with
patch 6/9.

Hans
