While running kselftest recently added gpio gpio-sim.sh test case the following warning was triggered on Linux next tag 20210330 tag running on arm64 juno and hikey devices.

This is still happening today on Linux next tag 20210407.

to the end of the loop in gpio_sim_setup_sysfs()?

If it fixes an issue I'll send a formal patch.
