linux-next: build warning after merge of the cgroup tree

[Stephen Rothwell]

Hi Tejun,

After merging the cgroup tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

kernel/cgroup/cgroup.c: In function 'init_cgroup_root':
kernel/cgroup/cgroup.c:1867:3: warning: ignoring return value of 'strscpy', 
declared with attribute warn_unused_result [-Wunused-result]
   strscpy(root->release_agent_path, opts->release_agent, PATH_MAX);
   ^
kernel/cgroup/cgroup.c:1869:3: warning: ignoring return value of 'strscpy', 
declared with attribute warn_unused_result [-Wunused-result]
   strscpy(root->name, opts->name, MAX_CGROUP_ROOT_NAMELEN);
   ^
kernel/cgroup/cgroup.c: In function 'cgroup_file_name':
kernel/cgroup/cgroup.c:1400:3: warning: ignoring return value of 'strscpy', 
declared with attribute warn_unused_result [-Wunused-result]
   strscpy(buf, cft->name, CGROUP_FILE_NAME_MAX);
