Subject: [PATCH -next 2/2] ASoC: SOF: ipc3: Use devm_kmemdup to replace devm_kmalloc + memcpy
Date: Thu, 10 Aug 2023 19:47:38 +0800	[thread overview]
Message-ID: <20230810114738.2103792-3-lizetao1@huawei.com> (raw)
In-Reply-To: <20230810114738.2103792-1-lizetao1@huawei.com>

Use the helper function devm_kmemdup() rather than duplicating its
implementation, which helps to enhance code readability.
