There are some log printing without a newline character. This
patch adds the missing newline characters.

Unless something changed in the last couple versions of the kernel, this is the
only line that actually changes anything. dev_* inserts a newline for every
call.
Admittedly, the rest of the file is pretty inconsistent, so if you really want
to make all these changes, I don't feel super strongly about it.

Not true.
Any printk without KERN_CONT inserts a newline
if the last character
emitted is not a newline.
dev_<level> uses can also be followed by pr_cont.
So this patch does reduce the possibility of
interleaved messages from multiple processes.

My mistake. Thanks for pointing that out.
