Subject: xsysace: Fix driver to use resource_size_t instead of unsigned long
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c14464bf796d5ead1e735225ead78c566d3344ae;p=linux-beck.git

xsysace: Fix driver to use resource_size_t instead of unsigned long

This patch is a bug fix to the SystemACE driver to use resource_size_t
for physical address instead of unsigned long.  This makes the driver
work correctly on 32 bit systems with 64-bit resources (e.g. PowerPC 440).
