The sh_rtc_set_irq_wake() function is only called from the suspend/resume handlers
that may be hidden, causing a harmless warning:
drivers/rtc/rtc-sh.c:724:13: error: 'sh_rtc_set_irq_wake' defined but not used [-Werror=unused-function]
static void sh_rtc_set_irq_wake(struct device *dev, int enabled)
The most reliable way to avoid the warning is to remove the existing #ifdef
and mark the two functions as __maybe_unused so the compiler can silently
drop all three when there is no reference.

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.
