Subject: x86: 0 -> NULL, for arch/x86_64
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=83e83d546cb1b6e3c566c97de97bd2397e22ab6c;p=openwrt%2Fstaging%2Fblogic.git

x86: 0 -> NULL, for arch/x86_64

When comparing a pointer, it's clearer to compare it to NULL than to 0.

[ tglx: arch/x86 adaptation ]
