From 815f1fcf2403454904cbbc5cf370df6bc300f392 Mon Sep 17 00:00:00 2001 From: Zhang Zekun Date: Tue, 27 Aug 2024 15:06:50 +0800 Subject: [PATCH] ASoC: audio-graph-card2: Use helper function of_get_child_count() of_get_child_count() can help to get the num of child directly and we don't need to manually count the child num. No functional change with this conversion.
