Does something not work with the following code in
msm_gpio_dbg_show_one()?


        if (!gpiochip_line_is_valid(chip, offset))
		return;

Hi Stephen,
I didnt realize that these changes are merged on tip. I was testing on 4.14 kernel.

https://lore.kernel.org/patchwork/patch/878107/
https://lore.kernel.org/patchwork/patch/878106/
https://lore.kernel.org/patchwork/patch/878109/

I will add "gpio-reserved-ranges" to internal platforms and this issue should not be observed.

-thanks, Prasad
