From d32cf9fbcb613a8f43e2211e964ccc8bb7271dcf Mon Sep 17 00:00:00 2001 From: Zhang Zekun Date: Fri, 16 Aug 2024 10:18:26 +0800 Subject: [PATCH] ALSA: aoa: Use helper function for_each_child_of_node() for_each_child_of_node can help to iterate through the device_node, and we don't need to use while loop. No functional change with this conversion.
