This series fixes MCLK resource leaks in the platform_clock_control()
implementations for bytcr_rt5640, bytcr_rt5651, and cht_bsw_rt5672.
In the SND_SOC_DAPM_EVENT_ON() path, clk_prepare_enable() is called to
enable MCLK, but subsequent failures in codec clock configuration (eg:
*_prepare_and_enable_pll1() or snd_soc_dai_set_sysclk()) return without
disabling the clock, leaking a reference.
Patches 1-3 fix this by adding the missing clk_disable_unprepare() calls
in the relevant error paths, ensuring proper symmetry between enable and
disable operations within the EVENT_ON scope.
Patch 4 moves unrelated logging changes into a separate patch and
standardizes error messages.
Changes in v6:
Place cleanup logic within SND_SOC_DAPM_EVENT_ON() scope
Avoid redundant condition checks in error paths
Split logging changes into a separate patch
Address review feedback from Mark Brown and Cezary Rojewski

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
Thanks Mark, appreciate it.
