Haotian Zhang 8f4e27e870 mtd: rawnand: lpc32xx_slc: fix GPIO descriptor leak on probe error and remove 
[ Upstream commit cdf44f1add ]

The driver calls gpiod_get_optional() in the probe function but
never calls gpiod_put() in the remove function or in the probe
error path. This leads to a GPIO descriptor resource leak.
The lpc32xx_mlc.c driver in the same directory handles this
correctly by calling gpiod_put() on both paths.

Add gpiod_put() in the remove function and in the probe error path
to fix the resource leak.

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 reStructuredText 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.
