Subject[PATCH v2 2/6] gpio: cdev: open-code to_gpio_chardev_data()
Date
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

This function is a wrapper around container_of(). It's used only once and
we will have a second notifier soon, so instead of having two flavors of
this helper, let's just open-code where needed.
