The comedi_error() function is just a wrapper around dev_err() that adds the dev->driver->driver_name prefix to the message and a terminating new-line character. The addition of the driver_name is just added noise and some of the users of comedi_error() add unnecessary additional new-line characters. Use dev_err() directly instead of comedi_error() to avoid any confusion and so that all the comedi generated kernel messages have the same format.
