    Subject[PATCH 2/4] scsi: lpfc: fix 32-bit format string warning
    On 32-bit architectures, we see a warning when %ld is used to
    print a size_t:

    In file included from drivers/scsi/lpfc/lpfc_init.c:62:
    drivers/scsi/lpfc/lpfc_init.c: In function 'lpfc_new_io_buf':
    drivers/scsi/lpfc/lpfc_logmsg.h:62:45: error: format '%ld' expects argument of type 'long int', but argument 5 has type 'unsigned int' [-Werror=format=]

    This is harmless, but portable code should just use %zd to
    avoid the warning.

    Fixes: 0794d601d174 ("scsi: lpfc: Implement common IO buffers between NVME and SCSI")
