Well, most of the time untested decoders have to be verified that they
actually decode everything correctly during the test implementation
(that's the purpose of the decoder test - to check that strace prints
what it is expected to print), so roughly every untested decoder requires
cross-checking with the kernel implementation, so, prctl, or UBI_*/PTP_*
ioctls could be examples of such decoders.
