[PATCH] cpumask.h: silence warning with -Wsign-compare

From: Brian W Hart
Date: Thu May 01 2014 - 15:30:26 EST


Silence the warning when building with -Wsign-compare when cpumask.h
is included:

include/linux/cpumask.h: In function âcpumask_parseâ:
include/linux/cpumask.h:603:26: warning: signed and unsigned type in conditional expression [-Wsign-compare]
int len = nl ? nl - buf : strlen(buf);
^
