[patch] 2.4.3-pre1: parport fix (nAutoFd)

[Tim Waugh]

Linus,

Here is a patch that makes 2.4.x's behaviour more closely match that
of 2.2.x when a nibble mode read goes wrong.  It prevents reading
processes from getting stuck in certain circumstances.

	* drivers/parport/ieee1284_ops.c (parport_ieee1284_read_nibble):
	Reset nAutoFd on timeout.  Matches 2.2.x behaviour.
