commite935dba111upstream. Since Linux v4.10 release (commit1d9174fbc5"PM / Runtime: Defer resuming of the device in pm_runtime_force_resume()"), pm_runtime_force_resume() function doesn't runtime resume device if it was not runtime active before system suspend. Thus, driver should not do any register access after pm_runtime_force_resume() without checking the runtime status of the device. To fix this issue, simply move s3c64xx_spi_hwinit() call to s3c64xx_spi_runtime_resume() to ensure that hardware is always properly initialized. This fixes Synchronous external abort issue on system suspend/resume cycle on newer Exynos SoCs.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
