5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: John Garry <john.garry@xxxxxxxxxx> [ Upstream commit 9806731db684a475ade1e95d166089b9edbd9da3 ] Add a common function to set the fields for a irq resource to disabled, which mimics what is done in acpi_dev_irqresource_disabled(), with a view to replace that function.
