[PATCH] target, iscsi: Fix up a few assignments

From: Jesper Juhl
Date: Sun Jan 15 2012 - 13:33:31 EST


A statement such as
struct iscsi_node_attrib *na = na = iscsit_tpg_get_node_attrib(sess);
has undefined behaviour since there are two assignments to 'na', strictly
speaking (the order in which side-effects from the assignments take place
is undefined since there's no intervening sequence point), and it looks
unintentional in any case.
