Rework the wakeup path inside notify_handler() to special case the buttons (KE_KEY) case instead of the switches case. In case of a button wake event we want to skip reporting this, mirroring how the drivers/acpi/button.c code skips the reporting in the wakeup case (suspended flag set) too. The reason to skip reporting in this case is that some Linux desktop-environments will immediately resuspend if we report an evdev event for the power-button press on wakeup. Before this commit the skipping of the button-press was done in a round-about way: In case of a wakeup the regular sparse_keymap_report_event() would always be skipped by an early return, and then to avoid not reporting switch changes on wakeup there was a special KE_SW path with a duplicate sparse_keymap_report_event() call. This commit refactors the wakeup handling to explicitly skip the reporting for button wake events, while using the regular reporting path for non button (switches) wakeup events. No intentional functional impact.

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.
