## Description

In the Linux kernel, the following vulnerability has been resolved:  ASoC: codecs: pcm512x: fix null-ptr dereference in pcm512x_overclock_xxx_put()  In the pcm512x chipset driver, pcm512x_overclock_xxx_put() is defined as a general mixer kcontrol instead of a DAPM kcontrol, so struct snd_soc_dapm_context must not be accessed via snd_soc_dapm_kcontrol_to_dapm().  This causes a NULL pointer dereference, so it must be modified to use snd_soc_component_to_dapm().
