![]() The s5p-cec driver returned CEC_TX_STATUS_ERROR for the NACK condition. Some digging into the datasheet uncovered the S5P_CEC_TX_STAT1 register where bit 0 indicates if the transmit was nacked or not. Use this to return the correct CEC_TX_STATUS_NACK status to userspace. This was the only driver that couldn't tell a NACK from another error, and that was very unusual. And a potential problem for applications as well. Tested with my Odroid-U3.
