From: David Matlack Date: Tue, 6 May 2014 04:02:36 +0000 (-0700) Subject: staging: slicoss: fix 64-bit isr address bug X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0783c636d1872123b68522b5afb257917c3d5aa9;p=linux-beck.git 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.
