On Dell Latitude 7275 the 5-button array is not exposed in the ACPI
tables, but notififies are still sent to the Intel HID device object
(device ID INT33D5) in response to power button actions. They were
ignored as the intel-hid driver was not prepared to take care of them
until recently.
Power button wakeup from suspend-to-idle was added in:
commit 635173a17b ("intel-hid: Wake up Dell Latitude 7275 from suspend-to-idle")
However power button suspend doesn't work yet on this platform so it
would be good to add it also.
On the affected platform (for which priv->array is NULL), add a new
upfront check against the power button press notification (0xCE) to
notify_handler(), outside the wakeup mode this time, which allows
reporting the power button press event and triggers the suspend. Also
catch and ignore the corresponding power button release notification
(0xCF) to stop it from being reported as an "unknown event" in the logs.

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.
