For S5Pv210 retention control, the driver stores the iomem pointer from
of_iomap() under a void pointer member. This makes sparse unhappy:
drivers/pinctrl/samsung/pinctrl-exynos.c:664:36: warning: incorrect type in argument 1 (different address spaces)
drivers/pinctrl/samsung/pinctrl-exynos.c:664:36: expected void const volatile [noderef] <asn:2>*addr
drivers/pinctrl/samsung/pinctrl-exynos.c:664:36: got void *
The iomem pointer is used safely (stored under priv by
s5pv210_retention_init(), used by s5pv210_retention_disable()) thus we
can add explicit casts to iomem to silence the warning.

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.
