cpumask.h: silence warning with -Wsign-compare
Silence the warning when building with -Wsign-compare when cpumask.h
is included:
include/linux/cpumask.h: In function ‘cpumask_parse’:
include/linux/cpumask.h:603:26: warning: signed and unsigned type in conditional expression [-Wsign-compare]
int len = nl ? nl - buf : strlen(buf);
^
V2: Rusty pointed out that unsigned should be used instead.
