[PATCH 0/1] Fix NULL pointer dereference

From: Pelle Nilsson

As I reported earlier, spi-altera driver is broken and causes a kernel
panic due to a NULL pointer dereference during first SPI
transaction. On a closer look, it turned out that the setup_transfer()
bitbang callback is mandatory when the txrx_bufs() callback is
present. It was therefore an error to remove it in commit
30af9b558a56. This patch simply adds back an empty implementation of
the callback.
