FYI 1:

Conversions of
printk(KERN_DEBUG ...)
to
pr_debug(...)
are not equivalent.

The first one is always placed into the object code
and emitted when the logging level is set appropriately.

The second one is only emitted if dynamic_debug is enabled
or if a #define DEBUG is set.

You should mention this change in the changelog.

In any case, for this code only, I think it's probably OK.

FYI 2:

There is a script that does these conversions and a few
other things: https://lwn.net/Articles/380161/
