From 0523cdc6e775494900c878af5f7eb7e90bb03f20 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Wed, 17 Oct 2018 13:11:11 +0530 Subject: [PATCH] PCI: keystone: Use ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW to get interrupt status Use ERR_IRQ_STATUS instead of ERR_IRQ_STATUS_RAW to get interrupt status. ERR_IRQ_STATUS_RAW has the status of the interrupts before masking whereas ERR_IRQ_STATUS has the status of the interrupts after masking. Since all the interrupts are unmasked here, use ERR_IRQ_STATUS.
