Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: xilinx: fix runtime PM leak on request error path
pm_runtime_get_sync() leaves the usage counter incremented even when it fails, and xgpio_request() returns the error without dropping it.
gpiolib does not call ->free() when ->request() fails, so xgpio_free(), which holds the only matching pm_runtime_put(), never runs. The reference is leaked and the controller can no longer runtime-suspend, so its clock stays enabled.
Switch to pm_runtime_resume_and_get(), which only increments the usage counter on success.
