Hello Güngör, You have a typo in the subject for this patch. "ssv_snp" should be "ssv_dnp" > > diff --git a/drivers/staging/comedi/drivers/ssv_dnp.c > b/drivers/staging/comedi/drivers/ssv_dnp.c > index 84b9f2a..4cd0f1b 100644 > --- a/drivers/staging/comedi/drivers/ssv_dnp.c > +++ b/drivers/staging/comedi/drivers/ssv_dnp.c > @@ -177,7 +177,7 @@ static int dnp_attach(struct comedi_device *dev, struct > comedi_devconfig *it) > struct comedi_subdevice *s; > int ret; > > - printk(KERN_INFO "comedi%d: dnp: ", dev->minor); > + pr_info("comedi%d: dnp: ", dev->minor); Where possible, fixes like this should use the dev_printk versions. For instance, this one would be: dev_info(dev->class_dev, "dnp:"); But, there is a cleaner fix for this file. See below. > dev->board_name = board->name; > > @@ -195,7 +195,7 @@ static int dnp_attach(struct comedi_device *dev, struct > comedi_devconfig *it) > s->insn_bits = dnp_dio_insn_bits; > s->insn_config = dnp_dio_insn_config; > > - printk("attached\n"); > + pr_info("attached\n"); There are only two printk's in this file, both in the "attach" routine. The first one does not have a "\n" and the function could exit without ever terminating the message. A better fix would be to merge the two messages into one "attached" message at the end of the function. You could also use the dev->board_name instead of the open coded string. Something like: dev_info(dev->class_dev, "%s: attached\n", dev->board_name); Also, the message should be moved so that it's the last thing that happens before the function returns.
