But see comment below.

OOI, what does pr_*() give us over printk()?  I presume it makes it easier
to selectively remove certain printk levels from the kernel image in the
name of size reduction.

Some people *may* insist that these long (>80 character) pr_err() lines be
split so they remain <80 in length.  This was the reason why the original
printk() call was split like it was.
