Commit896e97bf99("ACPI: EC: Clear GPE on interrupt handling only") broke suspend-to-idle at least on Dell XPS13 9360 and 9380. The problem is that acpi_ec_dispatch_gpe() must clear the EC GPE, because the EC GPE handler never runs when the system is in the suspend-to-idle state and if the EC GPE is not cleared by the suspend- to-idle loop, it is never cleared at all which leads to a GPE storm. This causes suspend-to-idle to burn energy instead of saving it which is potentially dangerous (the affected machines heat up rather badly when that happens). Addess this by making acpi_ec_dispatch_gpe() clear the EC GPE as it did before. Fixes:896e97bf99("ACPI: EC: Clear GPE on interrupt handling only") Tested-by: Rafael J.

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.
