Title
ASoC: codecs: wcd938x: fix missing mbhc init error handling
Summary
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
