      configfs: don't set buffer_needs_fill to zero if show() returns error · 3dc3afad
      Tal Shorer authored
      A confgifs attribute's show() callback is called once the first time
      the user attempts to read from it. If it returns an error, that
      error is returned to the user. However, the open file's
      buffer_needs_fill is still set to zero and consecutive read() calls
      will find an empty buffer that doesn't need filling and return 0 to
      the user. This could give the user the wrong impression that the
      attribute was read successfully.
      
      Fix this by not setting buffer_needs_fill if show() returns an error,
      making consecutive read() calls call show() again and either get an
      error again or get data.
