## Description

In the Linux kernel, the following vulnerability has been resolved:  pinctrl: pinconf-generic: Fix memory leak in pinconf_generic_parse_dt_config()  In pinconf_generic_parse_dt_config(), if parse_dt_cfg() fails, it returns directly. This bypasses the cleanup logic and results in a memory leak of the cfg buffer.  Fix this by jumping to the out label on failure, ensuring kfree(cfg) is called before returning.
