Depending on compiler version:
drivers/pinctrl/pinctrl-rza1.c: In function ‘rza1_pinctrl_probe’:
drivers/pinctrl/pinctrl-rza1.c:1260:5: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
if (ret)
^
Indeed, the result returned by platform_get_resource() was stored in
"res", not "ret". In addition, the correct error check would be
"if (!res)", as platform_get_resource() does not return an error code,
but returns NULL on failure.
However, as devm_ioremap_resource() verifies the validity of the passed
resource pointer anyway, the check can just be removed.

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.
