[PATCH 4/4] staging/lustre/libcfs: Fix kstrtouint return value check fix

[green]

From: Oleg Drokin <green@xxxxxxxxxxxxxx>

Apparently kstrtouint could return not just -EINVAL, but also -ERANGE,
so make sure we just check the return value for something negative.

Noticed by Dan Carpenter <dan.carpenter@xxxxxxxxxx>
