I cannot get rid of this error in the dmesg (unless I specify two

explained in [4]):

I forgot to specify:
the PB0 pin is not used by anything else.
# cat /sys/kernel/debug/pinctrl/1c20800.pinctrl/pinmux-pins
Pinmux settings per pin
Format: pin (name): mux_owner|gpio_owner (strict) hog?
pin 32 (PB0): UNCLAIMED
pin 33 (PB1): UNCLAIMED
[...]
And if I use other unclaimed pins (e.g. I tried with PC4 and PC7) the
same message appears.
Thanks!
