Message-Id: <20200116043947.12556-1-cw00.choi@samsung.com> Date: Thu, 16 Jan 2020 13:39:47 +0900 From: Chanwoo Choi <cw00.choi@...sung.com> To: linux-kernel@...r.kernel.org Cc: cw00.choi@...sung.com, chanwoo@...nel.org, myungjoo.ham@...sung.com Subject: [PATCH] extcon: Remove unneeded extern keyword from extcon.h 'extern' keyword is unneeded in extcon.h because public header file of extcon defines the function prototype.
