[ Upstream commitec0da06337] When meson_nfc_nand_chip_cleanup() is called, it will call: meson_nfc_free_buffer(&meson_chip->nand); nand_cleanup(&meson_chip->nand); nand_cleanup() in turn will call nand_detach() which calls the .detach_chip() which is here meson_nand_detach_chip(). meson_nand_detach_chip() already calls meson_nfc_free_buffer(), so we could double free some memory. Fix it by removing the unneeded explicit call to meson_nfc_free_buffer().

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.
