CVE-2026-98093

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

ASoC: fsl micfil: balance mclk enable/disable

hw params() enables mclk unconditionally and hw free() disables it unconditionally, but the PCM core does not guarantee 1:1 pairing: hw free() can run without hw params(), and hw params() can be called multiple times from the SETUP state. This triggers an "already disabled" WARN() in the first case and leaks an enable reference in the second, leaving the clock ungateable.

Guard both sides with the existing mclk flag, as fsl sai.c does with mclk streams.
