Interestingly, scripts/checkpatch.pl couldn't detect this problem.
I once used printk(KERN_ALERT...) and the script would properly warn me
that,

     WARNING: Prefer [subsystem eg: netdev]_alert([subsystem]dev, ... then dev_alert(dev, ... then pr_alert(...  to printk(KERN_ALERT .

I'll fix this issue when sending another version of the patches. Thank
you for the reminding!
