Subject: [PATCH 2/2] take 2: (was-kind-of: 3/5 SPI tx_default) 2.6.20-rc6

Just some trivial patches to make sure the existing drivers in
the official tree don't *silently* fail with the introduction of
default_tx_word.  Never tested in any way.  Not sure if this is
all, for example I didn't look in arch/*.
