Subject: [PATCH 4.4 21/28] extcon: Fix error handling in extcon_dev_register
Date: Mon, 5 Apr 2021 10:53:55 +0200 [thread overview]
Message-ID: <20210405085017.689281962@linuxfoundation.org> (raw)
In-Reply-To: <20210405085017.012074144@linuxfoundation.org>
From: Dinghao Liu <dinghao.liu@zju.edu.cn>
[ Upstream commit d3bdd1c3140724967ca4136755538fa7c05c2b4e ]
When devm_kcalloc() fails, we should execute device_unregister()
to unregister edev->dev from system.
Fixes: 046050f6e623e ("extcon: Update the prototype of extcon_register_notifier() with enum extcon")
