      scsi: aacraid: remove redundant zero check on ret · fbdab3e7
      由 Colin Ian King 提交于 
      The check for ret being zero is redundant as a few statements earlier we
break out of the while loop if ret is non-zero.  Thus we can remove the
zero check and also the dead-code non-zero case too.

      scsi: lpfc: use proper format string for dma_addr_t · 825c6abb
      由 Arnd Bergmann 提交于 
      dma_addr_t may be either u32 or u64, depending on the kernel configuration,
and we get a warning for the 32-bit case:

drivers/scsi/lpfc/lpfc_nvme.c: In function 'lpfc_nvme_ls_req':
drivers/scsi/lpfc/lpfc_logmsg.h:52:52: error: format '%llu' expects argument of type 'long long unsigned int', but argument 11 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]

printk has a special "%pad" format string that passes the dma address by
reference to solve this problem.

      scsi: lpfc: use div_u64 for 64-bit division · 90ec7c9d
      由 Arnd Bergmann 提交于 
      The new debugfs output causes a link error on 32-bit architectures:

ERROR: "__aeabi_uldivmod" [drivers/scsi/lpfc/lpfc.ko] undefined!

This code is not performance critical, so we can simply use div_u64().

[mkp: fixed up whitespace]
