Same thing for si2157 as Antti did earlier for tda18212:

There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and
driver is proper I2C driver.

While here, fix a typo ("unknown") in si2157_init.

The struct prototype is defined at the beginning of the code as
"si2157_ops" but the real struct is called "si2157_tuner_ops".

This is causing the name to be empty on this info msg: si2157 16-0060:
si2157: found a '' in cold state
