From 29681184da28babc990a66e197d27ab98f2027af Mon Sep 17 00:00:00 2001 From: Li Zetao Date: Thu, 10 Aug 2023 19:47:38 +0800 Subject: [PATCH] ASoC: SOF: ipc3: Use devm_kmemdup to replace devm_kmalloc + memcpy Use the helper function devm_kmemdup() rather than duplicating its implementation, which helps to enhance code readability.
