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. (NVD)
