From 997ba6573685451c37005a5b74a4baa3c16b5231 Mon Sep 17 00:00:00 2001 From: afzal mohammed Date: Wed, 4 Mar 2020 06:20:24 +0530 Subject: parisc: Replace setup_irq() by request_irq() request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().
