From 2519b7650e99d90643a7a20d623513de9c95a817 Mon Sep 17 00:00:00 2001 From: Chanwoo Choi Date: Thu, 11 Jun 2015 20:17:02 +0900 Subject: extcon: Remove optional print_state() function pointer of struct extcon_dev This patch removes the optional print_state() function pointer which included in 'struct extcon_dev' because the extcon must maintain the consistent name of extcon device on sysfs instead of inconsistent state of external connectors.
