Message-ID: <20230623100417.93592-4-brgl@bgdev.pl> (raw)
In-Reply-To: <20230623100417.93592-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Provide a helper wrapper around calling the platform's exit() callback.
This allows users to skip checking if the callback exists.
