From 704e8953d3e9db29d5d93c0bf6973d86fe15e679 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 13 Apr 2017 09:06:42 +0200 Subject: PCI/irq: Add pci_request_irq() and pci_free_irq() helpers These are small wrappers around request_threaded_irq() and free_irq(), which dynamically allocate space for the device name so that drivers don't need to keep static buffers for these around. Additionally it works with device-relative vector numbers to make the usage easier, and force the IRQF_SHARED flag on given that it has no runtime overhead and should be supported by all PCI devices.
