From d28af35b0c91eea1030c5fef1f8c0f21b97a7e03 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 6 Aug 2018 16:30:12 +0200 Subject: [PATCH] gpio: tb10x: Create local helper variables Create a local struct device *dev helper variable to make the code easier to read. Most GPIO drivers use "np" (node pointer) rather than "dn" (device node) to point to the device tree node. Let's follow this convention.
