Subject: [PATCH 1/3] extcon: Add stubs for extcon_register_notifier_all() functions
Date: Mon, 15 Feb 2021 19:06:08 +0900 [thread overview]
Message-ID: <20210215100610.19911-2-cw00.choi@samsung.com> (raw)
In-Reply-To: <20210215100610.19911-1-cw00.choi@samsung.com>
From: Krzysztof Kozlowski <krzk@kernel.org>
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).
Fixes: 815429b39d94 ("extcon: Add new extcon_register_notifier_all() to monitor all external connectors")
