Currently the alarmtimer registers a wake-up source unconditionally, regardless of the system having a (wake-up capable) RTC or not. Hence the alarmtimer will always show up in /sys/kernel/debug/wakeup_sources, even if it is not available, and thus cannot be a wake-up source. To fix this, postpone registration until a wake-up capable RTC device is added.

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.
