[ Upstream commit e9a8ba9769a0e354341bc6cc01b98aadcea1dfe9 ] The channels spfi->tx_ch and spfi->rx_ch are not set to NULL after they are released. As a result, they will be released again, either on the error handling branch in the same function or in the corresponding remove function, i.e. img_spfi_remove(). This patch fixes the bug by setting the two members to NULL.

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.
