CVE-2025-40154

In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

When an invalid value is passed via quirk option, currently bytcr_rt5640 driver only shows an error message but leaves as is. This may lead to unepxected results like OOB access.

This patch corrects the input mapping to the certain default value if an invalid value is passed.
