Date: Thu, 31 Dec 2020 09:52:52 +0100 From: Krzysztof Kozlowski <krzk@...nel.org> To: MyungJoo Ham <myungjoo.ham@...sung.com>, Chanwoo Choi <cw00.choi@...sung.com>, Hans de Goede <hdegoede@...hat.com>, linux-kernel@...r.kernel.org Cc: Timon Baetz <timon.baetz@...tonmail.com>, kbuild-all@...ts.01.org, Lee Jones <lee.jones@...aro.org>, Sebastian Reichel <sre@...nel.org>, Krzysztof Kozlowski <krzk@...nel.org>, kernel test robot <lkp@...el.com> Subject: [PATCH] extcon: Add stubs for extcon_register_notifier_all() functions Add stubs for extcon_register_notifier_all() function for !CONFIG_EXTCON case. This is useful for compile testing and for drivers which use EXTCON but do not require it (therefore do not depend on CONFIG_EXTCON).
