From 4bf27b7038c23fe789aa9bd553a6391cc33ccfa1 Mon Sep 17 00:00:00 2001 From: Vaishali Thakkar Date: Mon, 14 Sep 2015 23:19:35 +0530 Subject: [PATCH] extcon: axp288: Convert to using managed resources Use resource managed functions devm_usb_get_phy and devm_gpio_request to make error path simpler. To be compatible the change, various gotos are replaced with direct returns and unnecessary label gpio_req_failed is dropped. Also, remove function axp288_extcon_remove as it is now redundant.
