[PATCH] ASoC: meson: aiu: Fix resource leak

[Ethan Tidmore]

In snd_soc_register_component() error path, the aiu-formatter is not
being freed. Instead of returning now goto the err tag so the
aiu-formatter can properly be freed.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The patch modifies the error path to purportedly free the `aiu-formatter` resource by jumping to the `err` label, referencing commit 83b83024cdbfd. However, the `aiu-formatter` allocation and cleanup code (specifically `gx_formatter_create` and `gx_formatter_free`) does not exist in the codebase at this revision. The patch is a "ghost fix" attempting to resolve a resource leak for a feature that is missing in this tree.

ASoC: meson: aiu: Fix resource leak

This commit changes an error path in aiu_probe() to use a goto label
instead of returning directly. The commit message indicates this is to
ensure the aiu-formatter is properly freed when component registration
fails.

[Severity: Medium]
Is there a missing dependency for this patch, or is it an incomplete
backport?

The commit message mentions that the aiu-formatter is not being freed.
However, looking at aiu_probe() in this tree, there is no aiu-formatter
allocation or cleanup code present anywhere in the function.

[Severity: Medium]
At this error label, only snd_soc_unregister_component() is called,
and no formatter cleanup logic exists. Does this fix apply to a
different tree where the formatter feature is actually present?

This bug exists in linux-next. The AI is using the mainline.
