This should just be: printk(KERN_CONT " I/O port conflict\n"); If you want the message printed with KERN_ERR then don't bother with the continuation. There is no point in leaving out the trailing newline so that you can later do: printk(KERN_CONT "\n"); It's just silly. > return -EIO; > } > dev->iobase = iobase; > @@ -340,10 +342,11 @@ static int das6402_attach(struct comedi_device *dev, > /* should do a probe here */ > > irq = it->options[0]; > - printk(" ( irq = %u )", irq); > + printk(KERN_DEBUG " ( irq = %u )", irq); This looks like a continued line, so should be KERN_CONT. > ret = request_irq(irq, intr_handler, 0, "das6402", dev); > if (ret< 0) { > - printk("irq conflict\n"); > + printk(KERN_CONT "\n"); > + printk(KERN_DEBUG "( irq = %u)irq conflict\n", irq); > return ret; > } > dev->irq = irq; Please don't just go through and mindlessly fix checkpatch errors. Look at what the code is doing and try and actually fix it up properly. Especially when the code is in staging. These "fixes" don't really make the code any better. ~Ryan ^ permalink raw reply [flat|nested] 3+ messages in thread
