The patch titled Subject: scsi: mpt3sas: fix format overflow warning has been removed from the -mm tree. Its filename was scsi-mpt3sas-fix-format-overflow-warning.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: scsi: mpt3sas: fix format overflow warning We print the driver name into one string and then add and ID and copy it into a second string of the same length, at which point gcc complains about a possible overflow: drivers/scsi/mpt3sas/mpt3sas_scsih.c: In function '_scsih_probe': drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: error: '_cm' directive writing 3 bytes into a region of size between 1 and 32 [-Werror=format-overflow=] printf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id); ^~~~~~~~~ drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: note: directive argument in the range [0, 255] drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:2: note: 'sprintf' output between 5 and 38 bytes into a destination of size 32 sprintf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Making the first string shorter is sufficient to avoid the warning here, as we know it can only contain either "mpt2sas" or "mpt3sas".
