Hello,
I have found and error on drivers/gpio/gpiolib-cdev.c: the function lineevent_create doesn't call to init_waitqueue_head(&le->wait), which leads to a critical kernel error plus rebooting when trying to use GPIOs under an EVL enabled kernel.
On branch v5.10.y-evl-rebase the fix would be on line 2026:
2025 INIT_KFIFO(le->events);
2026 + init_waitqueue_head(&le->wait);
I have seen that this error is present also on the other branches.
Greetings
