Qiu Wenbo f0f7a3f542 platform/x86: int3472: Fix double free of GPIO device during unregister ... regulator_unregister() already frees the associated GPIO device. On ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to random failures when other drivers (typically Intel THC) attempt to allocate interrupts. The root cause is that the reference count of the pinctrl_intel_platform module unexpectedly drops to zero when this driver defers its probe. This behavior can also be reproduced by unloading the module directly. Fix the issue by removing the redundant release of the GPIO device during regulator unregistration.
