Hi,

@Bartosz, I have added you because you did some work on the gpio stuff 
in 6.18.

I run one APU box with latest gerne, and since I booted into 6.18.4 on 
January 9, I get multiple entries per second like
Jan 23 11:19:20 prom kernel: gpio-keys-polled gpio-keys-polled: failed to get gpio state: -52

This also applies to 6.18.6. 6.18.3 was still fine.

Do you have any idea what might be causing this and how to fix?

Greetings
Marc
