From: Bart Van Assche <[email protected]> [ Upstream commit 55d694275f41a1c0eef4ef49044ff29bc3999490 ]
Let the target core check the CMD_T_ABORTED flag instead of the SRP target driver. Hence remove the transport_check_aborted_status() call. Since state == SRPT_STATE_CMD_RSP_SENT is something that really should not happen, do not try to recover if srpt_queue_response() is called for an I/O context that is in that state. This patch is a bug fix because the srpt_abort_cmd() call is misplaced - if that function is called from srpt_queue_response() it should either be called before the command state is changed or after the response has been sent.
