i2c_hid_get_input floods
Yes problem appeared 2 times right after suspend, but not after every suspend.
(basically I'm not fluent what suspend mode is in use, I just closed laptop lid
to suspend and opened it back next day or after a hour. During all that time
laptop was suspended without external power source).

Do you have this issue after S3?
This issue generally happens to platforms that default to use s2idle but S3 is
in use.
BIOS doesn't turn off the touchpad power during S3, hence the IRQ gets pulled
up.
So I suggest use s2idle, or ask the platform vendor to solve the issue
from BIOS.

Thanks to your comment I also realized that journald still logs the
dmesg driver spam which results in bloated journald log files as well.
Few more steps is required to alleviate that:
1. sudo vi /etc/systemd/journald.conf
2. Uncomment Storage=auto and change it to Storage=none
3. Uncomment
That's a good point but unfortunately unloading and reloading the module
doesn't stop the messages from being produced on my system. Also, until
the issue is fixed, my aim was exactly to filter unnecessary events from
syslog to avoid bloated log files (kern.log and syslog) and unnecessary
events
Hmmm, filtering out syslog treats only a single symptom (dmesg, etc will
still have log spew) not to mention the events are still occurring
resulting in wasted CPU cycles. Why not just unload and reload the
module? It's much more straightforward...
