A few update suggestions were taken into account
from static source code analysis.
Markus Elfring (4):
Combine two function calls into one in show_cacheinfo()
Use seq_putc() in show_cpu_summary()
Replace six seq_printf() calls by seq_puts()
Combine two function calls into one at four places

A bit of data was put into a sequence by two separate function calls.
Print the same data by a single function call instead.
This issue was detected by using the Coccinelle software.

A single character (line break) should be put into a sequence.
Thus use the corresponding function "seq_putc".

Six strings which did not contain data format specifications should be put
into a sequence. Thus use the corresponding function "seq_puts".

I'm sorry, I wouldn't normally respond to this, but I was put on the Cc
after all so I'll give my feedback.
I think these patches are a waste of time and a resources.
It would be different if your patches fixed actual bugs. This is just
mindless code transformations that MAY in the best case save a few bytes
of code here and there (I don't know; you didn't say).
But the potential gains from these incredibly numerous and tiny patches
that don't fix anything are so small, it's a waste of time, bandwidth,
and mental capacity for you and for everybody involved.
I just searched my inbox for patches from you and you sent literally
_hundreds_ over the past few days, all doing this crazy printf/puts/putc
transformation.
Another bit of searching and I see that I'm not the first one giving you
this response:

I dare to point change possibilities out which correspond to a special error category.
There can be different opinions about their relevance for further software improvements.

Do you know the run time characteristics for the discussed functions good enough?

I suggest a bit of code reduction at various places once more.

I sent update suggestions in this scale since the year 2014.

I agree that the corresponding number could be remarkable.
But there are also other source code search patterns involved besides information
around these logging functions.

You are right that some agreements and disagreements were expressed already
(depending on the software area).

... they might also be acceptable if they came from a genuine newbie who does his
first patch, or if these patches represented genuine interest in the subsystem in
question, by being part of a larger work that adds new features or does some
meaningful code transformations.
They don't: they are Cocceline generated trivial patches from all around the
kernel, and there's probably thousands of such 'problems' in the kernel - do we
really want the churn of thousands of patches?
The cost of individual patches might be small, but their cumulative effect is
non-trivial if we add up all the extra noise and overhad this adds to the kernel
development flow.

I'm ignoring these minimal effort patches for subsystems I maintain and I suggest
other maintainers do the same.

How would you really react if such Linux development beginners would dare
to pick any of the shown software change opportunities up?

I am interested in various improvements where their size is varying between small
and big as usual.

These updates happened also several times.
