The following is left in the driver:


#ifdef DEBUG
printk(KERN_DEBUG "pc87360: Fan 1: mon=%d "
"ctrl=%d inv=%d\n", (confreg[0]>>2)&1,
(confreg[0]>>3)&1, (confreg[0]>>4)&1);
printk(KERN_DEBUG "pc87360: Fan 2: mon=%d "
"ctrl=%d inv=%d\n", (confreg[0]>>5)&1,
(confreg[0]>>6)&1, (confreg[0]>>7)&1);
printk(KERN_DEBUG "pc87360: Fan 3: mon=%d "
"ctrl=%d inv=%d\n", confreg[1]&1,
(confreg[1]>>1)&1, (confreg[1]>>2)&1);
#endif

Is there any reason why you didn't convert these to pr_debug()?

I know checkpatch.pl no longer complains about long lines when they
include a string, but 98 columns seems excessive to me. It would be
easy enough to spread over two lines.
