Yes, the error code comes from the card. And just as you expected,
opensc-exploring a non-existent DF will return the same SW.

The provided patch only works partially. The first error will pass
(-1216 -> -1201) but it will still fail on the second one. Below is
the resulting output from pkcs15-tool.
Do you need to patch card.c instead of dir.c?
