From dbc5623eb2898f5b5dcdc0b16077bb3f58629c78 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Sat, 22 Oct 2011 01:03:54 -0700 Subject: target: transport_subsystem_check_init cleanups Remove the now unnecessary extra call to transport_subsystem_check_init() in target_core_register_fabric(), and also merge transport_subsystem_reqmods() directly into transport_subsystem_check_init().
