From 0783c636d1872123b68522b5afb257917c3d5aa9 Mon Sep 17 00:00:00 2001 From: David Matlack Date: Mon, 5 May 2014 21:02:36 -0700 Subject: [PATCH] staging: slicoss: fix 64-bit isr address bug This patch fixes a bug that only manifests when the physical address of the interrupt status register is >4GB. Specifically, the driver was only telling the device about the lower 32 bits of the ISR. This patch adds the upper 32 bits.
