[GIT PULL] SCSI fixes for 5.5-rc3

[James Bottomley]

Four fixes and one spelling update, all in drivers: 2 in lpfc and the
rest in mp3sas, cxgbi and target.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Arnd Bergmann (1):
      scsi: lpfc: fix build failure with DEBUGFS disabled

Colin Ian King (1):
      scsi: lpfc: fix spelling mistakes of asynchronous

Dan Carpenter (1):
      scsi: mpt3sas: Fix double free in attach error handling

Israel Rukshin (1):
      scsi: target/iblock: Fix protection error with blocks greater than 512B

Varun Prakash (1):
      scsi: libcxgbi: fix NULL pointer dereference in cxgbi_device_destroy()
