In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp: add a null check for chip_pdev structure When acp platform device creation is skipped, chip->chip_pdev value will remain NULL. Add NULL check for chip->chip_pdev structure in snd_acp_resume() function to avoid null pointer dereference.
