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

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
