When you install/update linux kernel you can see these missing firmware warnings. These drivers are not necessary to run your system, at some point they where excluded from kernel. If these errors disturb you then you can get them from user repositories. The wd719x is a driver for "Western Digital WD7193, WD7197 and WD7296 SCSI cards" and aic94xx is the driver for "Adaptec SAS 44300, 48300, 58300 Sequencer".
