Latest 5.13 kernel in -prosed on Focal (20.04.3) gets the same gpio errors and warnings in dmesg and "journalctl -b" as with the current 5.11 HWE kernel.

Same error appears twice during boot. Here's the output from "journalctl -b"

They're both "gpiochip1 - GPIOs 0..-1", so why try again right after the first fails?
Does NOT appear on my Intel NUC Core i3. It's a 2013 model but runs the exact same kernel at least. Likely not on any Intel based motherboards.
To be clear this issue started with Kernel 5.8.0-63 NOT 5.11 (on Focal / 20.04 HWE LTS)
Well Ubuntu Kernel Bot, that's exactly what I did in comment #14 https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/1937897/ comments/ 14
