NFC: st21nfca: Change nfcid3 generation
nfcid3 is based on sensf_res value. target->sensf is never NULL as it is a table. Check the sensf_res_len instead to make sure sensf_res is set or not. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
