The EC sends an RTC host event when the RTC fires, but we don't need to treat that as a wakeup event here. The RTC class already properly handles activating and deactivating a wakeup source in rtc_update_irq() by calling pm_stay_awake() at the start of processing and pm_relax() once all expired RTC timers have been processed. This reduces one wakeup increment but not much else. I noticed this while debugging RTC wakeups and how they always incremented the wakeup count by two instead of one because this is duplicated.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
