From ed1054a02aa2323f1676093d6e58cde4484d8867 Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Fri, 5 Feb 2021 14:26:42 -0800 Subject: irqdomain: Mark fwnodes when their irqdomain is added/removed This allows fw_devlink to recognize irqdomain drivers that don't use the device-driver model to initialize the device. fw_devlink will use this information to make sure consumers of such irqdomain aren't indefinitely blocked from probing, waiting for the irqdomain device to appear and bind to a driver.
