scsi: ibmvscsis: Fix a stringop-overflow warning
[ Upstream commit d792d4c4fc866ae224b0b0ca2aabd87d23b4d6cc ]
There's currently a warning about string overflow with strncat:
drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c: In function 'ibmvscsis_probe':
drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c:3479:2: error: 'strncat' specified
bound 64 equals destination size [-Werror=stringop-overflow=]
strncat(vscsi->eye, vdev->name, MAX_EYE);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Switch to a single snprintf instead of a strcpy + strcat to handle this
cleanly.
