Following kernel warnings and crash notices on arm64 Rpi4 device while
running selftests: gpio on Linux mainline 6.3.0-rc1 kernel and Linux next.

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

Please refer to test log links for detailed test plan and kernel crash logs.
It is reproducible on arm64 juno-r2, Rpi4 and Qualcomm dragonboard 410c
and qemu-arm64.
