Mario Limonciello 4451e8e841 pinctrl: amd: Add IRQF_ONESHOT to the interrupt request On some systems the interrupt is shared between GPIO controller and ACPI SCI. When the interrupt is shared with the ACPI SCI the flags need to be identical. This should fix the GPIO controller failing to work after commit `7a36b901a6` ("ACPI: OSL: Use a threaded interrupt handler for SCI"). ``` [ 0.417335] genirq: Flags mismatch irq 9. 00000088 (pinctrl_amd) vs. 00002080 (acpi) [ 0.420073] amd_gpio: probe of AMDI0030:00 failed with error -16 ``` Cc: Rafael J.

README

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.
