CVE-2023-54230

A reference count leak was found in the ARM AMBA bus driver. When AMBA devices are created from device tree, the of_node reference count is incremented but never decremented in amba_device_release(), causing gradual memory leaks.

This primarily affects ARM/ARM64 systems using AMBA peripherals. The leak is small per device and accumulates slowly over device add/remove cycles. Normal system operation without frequent device changes is minimally impacted.
