From 14dbd54962f9679b7573f853814b8ff15b6ec407 Mon Sep 17 00:00:00 2001 From: Sangjung Woo Date: Mon, 21 Apr 2014 19:10:11 +0900 Subject: [PATCH] extcon: max14577: Use devm_extcon_dev_register() Use the resource-managed extcon device register function (i.e. devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device is attached with this function, that extcon device is automatically unregistered on driver detach. That reduces tiresome managing code.
