From e82bbd6761f7e313141c4033ebb79e3d397b6a9c Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Thu, 17 Aug 2023 13:42:34 +0200 Subject: [PATCH] gpio: cdev: open-code to_gpio_chardev_data() 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.
