[PATCH] ASoC: cs35l41: Always return 0 when a subsystem ID is found

[Eric Naim <dnaim@cachyos.org>]

When trying to get the system name in the _HID path, after successfully
retrieving the subsystem ID the return value isn't set to 0 but instead
still kept at -ENODATA, leading to a false negative:

[   12.382507] cs35l41 spi-VLV1776:00: Subsystem ID: VLV1776
[   12.382521] cs35l41 spi-VLV1776:00: probe with driver cs35l41 failed with error -61

Always return 0 when a subsystem ID is found to mitigate these false
negatives.
