ftrace: Clean up __seq_open_private() return check
The return status check of __seq_open_private() is rather strange:
iter = __seq_open_private();
if (iter) {
/* do stuff */
}
return iter ? 0 : -ENOMEM;
It makes much more sense to do the return of failure right away:
iter = __seq_open_private();
if (!iter)
return -ENOMEM;
/* do stuff */
return 0;
This clean up will make updates to this code a bit nicer.
