No, not really.

pr_debug differs from printk(KERN_DEBUG in that
pr_debug is only enabled with a #define DEBUG
or CONFIG_DYNAMIC_DEBUG setting.

I did not want to convert any of the printks
with KERN_DEBUG in this pass as that would
change the message logging by requiring
dynamic debugging be included in the CONFIG.

A subsequent pass converting these uses will
be done if or after these initial patches are
applied.

thanks, Joe
