From 598cf961d82a12afa3ccbed9645edae2275b76f3 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Tue, 3 Sep 2024 19:09:37 -0700 Subject: [PATCH] lib: utils/gpio: Remove fdt_gpio_driver() function This function looks up a chip's driver by matching known drivers against chip->driver, but that is equivalent to using chip->driver directly.
