2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Tilman Schmidt <[email protected]> commit f3d531b99fb30945b4a64d6e2e86e1e62605aca5 upstream. In transparent data reception, avoid a NULL pointer dereference in case an skbuff cannot be allocated, remove an inappropriate call to the HDLC flush routine, and correct the accounting of received bytes for continued buffers.
