From f6ab5a92acc78371fc088075b64bd394d1f0d45f Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 14 Jun 2017 21:28:43 -0600 Subject: dm: scsi: Add operations for SCSI devices The SCSI uclass currently has no operations. It just uses the global SCSI functions. Fix this by adding operations to the only two drivers that use the uclass, and replacing the global functions with those defined locally in the SCSI code.
