[PATCH 5.4 147/270] ASoC: meson: fixes the missed kfree() for axg_card_add_tdm_loopback

[Greg Kroah-Hartman]

From: Jing Xiangfeng <jingxiangfeng@xxxxxxxxxx>

[ Upstream commit bd054ece7d9cdd88e900df6625e951a01d9f655e ]

axg_card_add_tdm_loopback() misses to call kfree() in an error path. We
can use devm_kasprintf() to fix the issue, also improve maintainability.
So use it instead.
