From e260cfe6fb503292f183a43b51177664b222435d Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Thu, 4 Aug 2022 10:54:21 +0800 Subject: irqchip/loongson-eiointc: Fix irq affinity setting In multi-node case, csr_any_send() should set EIOINTC_REG_ENABLE of the first core of target node, not the first core of the whole.
