- core_tpg_pre_addlun() returns always ERR_PTR() or the pointer, never NULL. The additional check for NULL in core_dev_add_lun() is not required. - core_tpg_pre_dellun() returns always ERR_PTR() or the pointer, never NULL. The check for NULL in core_dev_del_lun() is wrong. The third argument (int *) is never used, remove it. - core_dev_add_lun() returns always NULL or the pointer, never ERR_PTR. The check for IS_ERR() is not required. (nab: Convert core_dev_add_lun() use err.h macros for failure handling to be consistent with the rest of target_core_fabric_configfs.c callers) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: <stable@vger.kernel.org> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
