Subject: [PATCH 4.4 09/17] ALSA: jack: Check the return value of kstrdup()
Date: Mon, 27 Dec 2021 16:27:04 +0100 [thread overview]
Message-ID: <20211227151316.260151757@linuxfoundation.org> (raw)
In-Reply-To: <20211227151315.962187770@linuxfoundation.org>
From: Xiaoke Wang <xkernel.wang@foxmail.com>
commit c01c1db1dc632edafb0dff32d40daf4f9c1a4e19 upstream.
kstrdup() can return NULL, it is better to check the return value of it.
