-* coding style does not fully comply with the kernel style guide.
-* still TODOs, annotated in the code
* currently the code introduces new IOCTLs. I'm afraid this is a bad idea.
-> Replace this with another interface, hints are welcome!
* Some missing data (marked with ###) needs to be added in the documentation
+* Change (struct pi433_tx_cfg)->bit_rate to be a u32 so that we can support
+ bit rates up to 300kbps per the spec.
