Subject: [PATCH] extcon: Remove unneeded extern keyword from extcon.h
Date: Thu, 16 Jan 2020 13:39:47 +0900	[thread overview]
Message-ID: <20200116043947.12556-1-cw00.choi@samsung.com> (raw)
In-Reply-To: <CGME20200116043228epcas1p11a74c5935b015ec85fc61da8cf12681f@epcas1p1.samsung.com>

'extern' keyword is unneeded in extcon.h because public header file
of extcon defines the function prototype.
