In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: wcd938x: fix missing mbhc init error handling
MBHC initialisation can fail so add the missing error handling to avoid
dereferencing an error pointer when later configuring the jack:
Unable to handle kernel paging request at virtual address fffffffffffffff8
pc : wcd_mbhc_start+0x28/0x380 [snd_soc_wcd_mbhc]
lr : wcd938x_codec_set_jack+0x28/0x48 [snd_soc_wcd938x]
