Summary
regulator: core: fix NULL dereference on unbind due to stale coupling data
Details

In the Linux kernel, the following vulnerability has been resolved:

regulator: core: fix NULL dereference on unbind due to stale coupling data

Failing to reset couplingdesc.ncoupled after freeing coupled_rdevs can lead to NULL pointer dereference when regulators are accessed post-unbind.

This can happen during runtime PM or other regulator operations that rely on coupling metadata.

For example, on ridesx4, unbinding the 'reg-dummy' platform device triggers a panic in regulatorlockrecursive() due to stale coupling state.

Ensure n_coupled is set to 0 to prevent access to invalid pointers.
