[ Upstream commit 26cfc0dbe43aae60dc03af27077775244f26c167 ]
The function wait_for_completion_interruptible_timeout will return
-ERESTARTSYS immediately when receiving SIGKILL signal which is sent
by "jffs2_gcd_mtd" during umounting jffs2. This will break the SPI memory
operation because the data transmitting may begin before the command or
address transmitting completes. Use wait_for_completion_timeout to prevent
the process from being interruptible.
Fixes: 67dca5e580f1 ("spi: spi-mem: Add support for Zynq QSPI controller")

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.
