If anyone has any objections, please let me know. ------------------ From: Haotian Zhang [ Upstream commit 636f4618b1cd96f6b5a2b8c7c4f665c8533ecf13 ] 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.
