As compiler spotted out, there is the potential NULL-dereference in the code when dc-measure OF is given for other than 43130/43131: sound/soc/codecs/cs43130.c:2089:18: warning: ‘hpload_seq’ may be used uninitialized in this function [-Wmaybe-uninitialized]
Warn it and return before triggering Oops.
