Hi,
After rebasing my samsung,coreprimevelte patchset to v6.16-rc5 (from v6.14), I
found that the board would not successfully boot. Through serial I managed to
extract this oops (stack trace decoded):

I went through recent commits to sm5502, gpiolib and finally gpio-pxa to check
whether any of them could be causing issues. Eventually I stumbled upon
20117cf426b6 ("gpio: pxa: Make irq_chip immutable") and reverted it locally,
after which the board started booting again.

Hello,
Friendly ping on this issue. The issue still occurs on v6.16 and is still
fixed by reverting commit 20117cf426b6. I have found that the root cause seems
to be a bad pointer in gpio_chip->gpio_device.owner, but was not able to
figure out why this happens nor why this only happens when the IRQ chip is
immutable. Is there anything else I can do to try and get this resolved?
Regards,
