![]() After calling platform_set_drvdata(pdev, xqspi) in probe, the return
value of dev_get_drvdata(dev) is a pointer to struct zynqmp_qspi but
not struct spi_controller. A wrong structure type passing to the
functions spi_controller_suspend/resume will hang the system.
And we should check the return value of spi_controller_suspend, if
an error is returned, return it to PM subsystem to stop suspend.
Also, GQSPI_EN_MASK should be written to GQSPI_EN_OFST to enable
the spi controller in zynqmp_qspi_resume since it was disabled in
zynqmp_qspi_suspend before.

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.
