6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Vladimir Riabchun [ Upstream commit c0b7da13a04bd70ef6070bfb9ea85f582294560a ] In qla24xx_els_dcmd_iocb() sp->free is set to qla2x00_els_dcmd_sp_free(). When an error happens, this function is called by qla2x00_sp_release(), when kref_put() releases the first and the last reference. qla2x00_els_dcmd_sp_free() frees fcport by calling qla2x00_free_fcport(). Doing it one more time after kref_put() is a bad idea.
