Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rockchip: rockchip_pdm: Handle runtime PM resume failures in set_fmt
rockchip_pdm_set_fmt() calls pm_runtime_get_sync() before accessing
hardware registers, but ignores its return value.
If the runtime resume fails, the function continues to perform register
accesses while the device state is undefined.
Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() and
return early on failure to avoid unpowered register accesses.
