| Enable reference count tracking for DPLL devices and pins. | |
| This helps debugging reference leaks and use-after-free bugs | |
| by recording stack traces for each get/put operation. | |
| The tracking information is exposed via debugfs at: | |
| /sys/kernel/debug/ref_tracker/dpll_device_* | |
| /sys/kernel/debug/ref_tracker/dpll_pin_* | |
| If unsure, say N. | |
