Hi.

When i plug an USB HID device with the DELIMITER tag in its report 
descriptor, the device doesn't load.

The problem comes from the "return 1" in the DELIMITER switch of the 
local tags parsing.

I join a trivial patch that return no error when encounter the 
DELIMITER tag.

Please review it.


Regards.

Paul.

Interesting; apparently this bug has been there for ages. Please send me 
your Signed-off-by: line as documented in Documentation/SubmittingPatches 
so that I can queue your patch.
