Haotian Zhang 636f4618b1 regulator: fixed: fix GPIO descriptor leak on register failure
In the commit referenced by the Fixes tag,
devm_gpiod_get_optional() was replaced by manual
GPIO management, relying on the regulator core to release the
GPIO descriptor. However, this approach does not account for the
error path: when regulator registration fails, the core never
takes over the GPIO, resulting in a resource leak.

Add gpiod_put() before returning on regulator registration failure.
