[PATCH v4 0/4] ASoC: Intel: Fix MCLK leaks in

[aravindanilraj0702]

From: Aravind Anilraj <aravindanilraj0702@xxxxxxxxx>

In three Intel ASoC board drivers, the EVENT_ON path in
platform_clock_control() enables MCLK via clk_prepare_enable() but fails
to call clk_disable_unprepare() on subsequent error paths, leaking the
clock reference.

v4: Split dev_err formatting fix into a separate patch 4 as suggested by Mark Brown. Add return code to the error message for better diagnostics.

v3: Restored missing clk_disable_unprepare() guard in patch 2 that was
accidently dropped during v2 rebase.

v2: Guard clk_disable_unprepare() with SND_SOC_DAPM_EVENT_ON() to avoid
calling it in the EVENT_OFF error path where MCLK was never enabled.

Fix this across all three affected drivers.
