[PATCH] sil24: implement tf_read callback
Hello, guys. This patch implements ->tf_read callback for sil24. It didn't use to be necessary but new ata_gen_fixed_sense now makes use of ->tf_read callback. This patch is taken from Edward Falk's driver. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
