NFC: st21nfca: Improve load_session
In case anybody uses previous patchset with the CLF, add a check to make sure missing pipe are created. st21nfca returns its pipe list in the creation order (most recent latest). Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
