From 40d50cf7ca956183f3a573bc21082e1c7d04fa7b Mon Sep 17 00:00:00 2001 From: Roman Fietze Date: Tue, 8 Dec 2009 02:39:50 +0000 Subject: powerpc: Make "intspec" pointers in irq_host->xlate() const Writing a driver using SCLPC on the MPC5200B I detected, that the intspec arrays to map irqs to Linux virq cannot be const, because the mapping and xlate functions only take non const pointers. All those functions do not modify the intspec, so a const pointer could be used.
