Michael Walle 09f9946235 NFC: nxp-nci: Don't issue a zero length i2c_master_read() ... commit eddd95b9423946aaacb55cac6a9b2cea8ab944fc upstream. There are packets which doesn't have a payload. In that case, the second i2c_master_read() will have a zero length. But because the NFC controller doesn't have any data left, it will NACK the I2C read and -ENXIO will be returned. In case there is no payload, just skip the second i2c master read.
