Subject: [PATCH 5.15 263/667] ASoC: rk3328: fix disabling mclk on pclk probe failure

From: Nicolas Frattaroli <frattaroli.nicolas@...il.com>

[ Upstream commit dd508e324cdde1c06ace08a8143fa50333a90703 ]

If preparing/enabling the pclk fails, the probe function should
unprepare and disable the previously prepared and enabled mclk,
which it doesn't do. This commit rectifies this.
