Paul Gortmaker a8a3593185 video: Add export.h for THIS_MODULE/EXPORT_SYMBOL to drivers/video
With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.
