From a718ed2cfed0faba89b4bb9fa9f1ab5957891de9 Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Mon, 22 Feb 2016 17:43:28 +0530 Subject: [PATCH] gpio: 74xx-mmio: Use devm_gpiochip_add_data() for gpio registration Use devm_gpiochip_add_data() for GPIO registration and remove the call for gpiochip_remove() from error path. Also remove the need of driver callback .remove.
