Haotian Zhang 31a148f1d0 regulator: fixed: fix GPIO descriptor leak on register failure
[ 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.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
