[pkg-opensc-commit] [libp11] 107/239: "frain" reported: libp11 fails at enumerating tokens if a PKCS#11 library returns CKR_TOKEN_NOT_RECOGNIZED on a C_GetTokenInfo call. The attached patch causes libp11 to treat slots containing unrecognized tokens as empty slots during token enumeration, letting the enumeration succeed even if unrecognized tokens are present.
