Description
A flaw was found in the Linux kernel's Arizona General Purpose Input/Output (GPIO) driver. This issue allows a local user to cause a resource leak by triggering an error during persistent GPIO line configuration. Specifically, if an internal register update fails while changing pin direction from input to output, the runtime Power Management (PM) reference counter is not decremented. As a result, the parent device is prevented from entering low-power suspend states, causing continuous power consumption.
