[ Upstream commit a90903c2a3c38bce475f46ea3f93dbf6a9971553 ]
devm_pm_runtime_enable() can fail due to memory allocation. The current
code ignores its return value, potentially causing runtime PM operations
to fail silently after autosuspend configuration.
Check the return value of devm_pm_runtime_enable() and return on failure.
Fixes: 909fac05b9 ("spi: add support for Amlogic A1 SPI Flash 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.
