Function nxp_nci_i2c_write currently assumes in case of I2C bus NACK that the NFC device is in stand-by mode and will retry the I2C transaction after a pause. This assumes that the first failed I2C transaction will wake-up the device. This is done by checking on EREMOTEIO, which is wrong. According to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately the NOACK return code is currently inconsistent across various I2C host controller drivers. So only check for the generic error case instead. This is a temporary fix. As soon as all I2C bus master drivers are fixed to consistently return 'ENXIO', then we can do the specific error check again.
