From c37927a203fa283950f6045602b9f71328ad786c Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 11 Jul 2024 12:20:04 +0200 Subject: genirq: Set IRQF_COND_ONESHOT in request_irq() The callers of request_irq() don't care about IRQF_ONESHOT because they don't provide threaded handlers, but if they happen to share the IRQ with the ACPI SCI, which has a threaded handler and sets IRQF_ONESHOT, request_irq() will fail for them due to a flags mismatch. Address this by making request_irq() add IRQF_COND_ONESHOT to the flags passed to request_threaded_irq() for all of its callers.
