| |
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
