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().
