[PATCH] cpufreq: governor: Free dbs_data directly when gov->init() fails

From: Liao Chang
Date: Fri Aug 25 2023 - 21:26:51 EST


Due to the kobject embedded in the dbs_data doest not has a release()
method yet, it needs to use kfree() to free dbs_data directly when
governor fails to allocate the tunner field of dbs_data.
