mainlining shenanigans
The GPD win and its sibling the GPD pocket (99% the same electronics in a different case) use a PCI wifi card. But the ACPI tables on both variants contain a bug where the SDIO MMC controller for SDIO wifi cards is enabled despite this. This SDIO MMC controller has a PCI0.SDHB.BRC1 child-device which _PS3 method sets a GPIO causing the PCI wifi card to turn off. At the moment there is a pretty ugly kludge in the sdhci-acpi.c code, just to work around the bug in the DSDT of this single design. This can be solved cleaner/simply with a quirk overriding the _STA return of the broken PCI0.SDHB.BRC1 PCI0.SDHB.BRC1 child with a status value of 0, so that its power_manageable flag gets cleared, avoiding this problem. Note that even though it is not used, the _STA method for the MMC controller is deliberately not overridden. If the status of the MMC controller were forced to 0 it would never get suspended, which would cause these mini-laptops to not reach S0i3 level when suspended.

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.
