Hi Mark, Krzysztof,

It appears that commit daad134d6649 ("regulator: core: Request GPIO
before creating sysfs entries") breaks boot on tegra124-nyan-big in
-next today.

Looking at the change, it does not appear that the exit path has been
updated correctly and so if a regulator is deferred then there is a
crash in the exit path. I am not sure that there is a simple way to
workaround this because of fix from commit 53032dafc6b9 ("regulator
core: fix double-free in regulator_register() error path") unless we
move regulator_ena_gpio_free() into regulator_dev_release().

Cheers
Jon
