Subject: iscsi-target: Fix iscsit_get_tpg_from_np tpg_state bug
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a2a99cea5ec7c1e47825559f0e75a4efbcf8aee3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

iscsi-target: Fix iscsit_get_tpg_from_np tpg_state bug

This patch fixes a bug in iscsit_get_tpg_from_np() where the
tpg->tpg_state sanity check was looking for TPG_STATE_FREE,
instead of != TPG_STATE_ACTIVE.

The latter is expected during a normal TPG shutdown once the
tpg_state goes into TPG_STATE_INACTIVE in order to reject any
new incoming login attempts.
