There are three drivers with *it913x name on it, and they all belong to the same device: a tuner, at it913x.c; a frontend: it913x-fe.c; a bridge: it913x.c, renamed to dvb_usb_it913x by the building system. This is confusing. Even more confusing are the two .c files with the same name under different directories, with different contents and different functions. So, prepend the tuner one. This also breaks the out-of-tree compilation system.
