From e55aeb6ba4e8cc3549bff1e75ea1d029324bce21 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 9 Aug 2016 16:18:51 +0200 Subject: [PATCH] of/irq: Mark interrupt controllers as populated before initialisation That way the init callback may clear the flag again, in case of drivers split between early irq chip and a normal platform driver.
