From d8e925dc8850c01e36e6b2acb08ed0fbdc38b9f1 Mon Sep 17 00:00:00 2001 From: "Moore, Eric" Date: Mon, 16 Jan 2006 18:53:06 -0700 Subject: [PATCH] [SCSI] fusion: spi bus reset when driver loads This patch is for spi. This issues bus reset when driver loads. Handling cases when initator has negotiated for packetized, and target negotiated for non-packetized; effectly this bus reset is getting both target and initiator on the same sheet of music.
