Description

In the Linux kernel, the following vulnerability has been resolved: mfd: arizona: Fix regulator resource leak on wm5102_clear_write_sequencer() failure The wm5102_clear_write_sequencer() helper may return an error and just return, bypassing the cleanup sequence and causing regulators to remain enabled, leading to a resource leak. Change the direct return to jump to the err_reset label to properly free the resources.
