From ea0c80d1764449acf2f70fdb25aec33800cd0348 Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Thu, 24 Sep 2020 15:17:49 +0800 Subject: genirq: Add stub for set_handle_irq() when !GENERIC_IRQ_MULTI_HANDLER In order to avoid compilation errors when a driver references set_handle_irq(), but that the architecture doesn't select GENERIC_IRQ_MULTI_HANDLER, add a stub function that will just WARN_ON_ONCE() if ever used.
