Subject: [PATCH 2/2] USB: ncevibrator: simplify tv_probe
Date: Thu, 11 Aug 2022 10:53:42 +0800	[thread overview]
Message-ID: <20220811025346.113199-2-dzm91@hust.edu.cn> (raw)
In-Reply-To: <20220811025346.113199-1-dzm91@hust.edu.cn>

From: Dongliang Mu <mudongliangabcd@gmail.com>

The function tv_probe does not need to invoke kfree when the
allocation fails. So let's simplify the code of tv_probe.
