Description

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: rt1011: Use component to get the dapm context in spk_mode_put The correct helper to use in rt1011_recv_spk_mode_put() to retrieve the DAPM context is snd_soc_component_to_dapm(), from kcontrol we will receive NULL pointer.
