This fixes a double free on unload, right?

The patch
ASoC: mediatek: mt2701: drop unnessary snd_soc_unregister_component()
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

Hi Wei
It's not necessary to unregister a component registered with devm_snd_soc_register_component().

I guess, below patch is using normal snd_soc_add_component() not devm_ version, and above unregister is for it ? And I think f1b5bf07365d patch is not related to youur patch (It is "platform" replace patch, your one is for "component" patch).

static int mt2701_afe_add_component(struct mtk_base_afe *afe) { struct snd_soc_component *component;
component = kzalloc(sizeof(*component), GFP_KERNEL); if (!component) return -ENOMEM;
component->regmap = afe->regmap;
return snd_soc_add_component(afe->dev, component, &mt2701_afe_pcm_dai_component, mt2701_afe_pcm_dais, ARRAY_SIZE(mt2701_afe_pcm_dais)); }
