Subject: [PATCH v2 1/3] Staging: comedi: fix printk issue in cb_pcidio.c

This is a patch to the cb_pcidio.c file that fixes up a printk warning
found by the checkpatch.pl tool

Signed-off-by: Ravishankar Karkala Mallikarjunayya <ravishankar.km@...enturtles.in>
---
 v2: printk strings are fixed as suggested by Ryan Mallon.
 Converted printks to pr_levels> and 2 prinks are removed from the
 function. i.e. printk("comedi%d: cb_pcidio: \n", dev->minor);
 printk("comedi%d: cb_pcidio: remove\n", dev->minor);
 
 v1: Used dev_<levels> instead of printks which is not possible because
 In the function, pcidev is initialized to NULL so the Earlier patch
 was broken.
