media: rc: self test for IR encoders and decoders
ir-loopback can transmit IR on one rc device and check the correct
scancode and protocol is decoded on a different rc device. This can be
used to check IR transmission between two rc devices. Using rc-loopback,
we use it to check the IR encoders and decoders themselves.
No hardware is required for this test.
