Changelog should not be empty even for trivial patches.

This changes 2 of X in the file. Why only these 2? And no, I'm not
encouraging to resend with a full file changes. We do these modernizations
to new APIs only while changing the code for other reasons, not separately,
if there's nothing wrong otherwise with the legacy api. The churn isn't
worth it.

Thanks for the feedback. I understand now that printk→pr_* cleanups
are not accepted as standalone cosmetic patches. I will drop this patch
and focus on patches with real fixes.

Best regards,
