Message-id: <1443666286-21522-3-git-send-email-cw00.choi@samsung.com> Date: Thu, 01 Oct 2015 11:24:43 +0900 From: Chanwoo Choi <cw00.choi@...sung.com> To: linux-kernel@...r.kernel.org Cc: cw00.choi@...sung.com, myungjoo.ham@...sung.com Subject: [PATCH 2/5] extcon: gpio: Remove duplicate data from struct gpio_extcon_data There are duplicate data between struct gpio_extcon_data and struct gpio_extcon_platform_data. This patch removes them from struct gpio_extcon_data. Instead, this patch add pdata field to struct gpio_extcon_data.
