[PATCH] cocci: Provide script to find i2c_tables missing exports

[Kieran Bingham]

Adds MODULE_DEVICE_TABLE(i2c, ...) to correctly export tables in i2c drivers
---
Ahem, My appologies, I wrongly sent the patch I was working on for OF tables,

Of course this is the correct patch for adding the i2c_device_id exports,
which I think is what you are currently looking at
