Staging: comedi: change pr_err to dev_err in __unioxx5_digital_write
This is a patch which subsitutes pr_err with the preferred dev_err for device drivers in __unioxx5_digital_write. The function definition of __unioxx5_digital_write has been changed to take the pointer to the struct comedi_subdevice as a parameter instead of the pointer to struct unioxx5_subd_priv. The pointers to the stuct device and the struct unioxx5_subd_priv are obtained through the pointer to the struct comedi_subdevice in this function. The function call to __unioxx5_digital_write in unioxx5_subdev_write has been changed to pass the pointer to the struct comedi_subdevice Signed-off-by: Conrad Gomes <conrad.s.j.gomes@gmail.com> Reviewed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
