From 797b13a7de957792c1b4773aa2cc3dab4621fd9c Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Tue, 1 Sep 2026 09:04:48 +0200 Subject: [PATCH] irqdomain: Delete irq_domain_add_linear() 7.3-rc1 is free of calls to irq_domain_add_linear(), so it can be finally deleted. According to Dongliang Mu, the related paragraph in the Chinese docs is now obsolete. So drop it completely.
