    configfs: Allow ->make_item() and ->make_group() to return detailed errors. · 11c3b792
    Joel Becker authored
    The configfs operations ->make_item() and ->make_group() currently
    return a new item/group.  A return of NULL signifies an error.  Because
    of this, -ENOMEM is the only return code bubbled up the stack.
    
    Multiple folks have requested the ability to return specific error codes
    when these operations fail.  This patch adds that ability by changing the
    ->make_item/group() ops to return an int.
    
    Also updated are the in-kernel users of configfs.
