From 926347061ef1f4d3873829fd1960c6e4b965aa9f Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Fri, 23 Jun 2017 01:18:12 -0500 Subject: target: break up free_device callback With this patch free_device is now used to free what is allocated in the alloc_device callback and destroy_device tears down the resources that are setup in the configure_device callback. This patch will be needed in the next patch where tcmu needs to be able to look up the device in the destroy callback.
