Applied to 5.14/scsi-fixes, thanks! [1/1] scsi: Don't print target alloc failed print for ENXIO https://git.kernel.org/mkp/scsi/c/85601d88eccc

Don't print 'target allocation failed' message if the driver returns -ENXIO error value for target_alloc callback function. Driver returns -ENXIO value if corresponding H:C:T:L entry is empty. Removing this print reduces the scan time if the user issues SCAN_WILD_CARD scan operation through sysfs parameter on a host with a lot of empty H:C:T:L entries.
