CVE-2025-39892

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

ASoC: soc-core: care NULL dirver name on snd_soc_lookup_component_nolocked()

soc-generic-dmaengine-pcm.c uses same dev for both CPU and Platform.
In such case, CPU component driver might not have driver->name, then
snd_soc_lookup_component_nolocked() will be NULL pointer access error.
Care NULL driver name.
