[GIT PULL] SCSI fixes for 5.1-rc5

[GIT PULL] SCSI fixes for 5.1-rc5

[James Bottomley]

Three minor fixes: two obvious ones in drivers and a fix to the SG_IO
path to correctly return status on error.

The patch is available here:

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

The short changelog is:

Christoph Hellwig (1):
      scsi: aic7xxx: fix EISA support

Jaesoo Lee (1):
      scsi: core: set result when the command cannot be dispatched

Saurav Kashyap (1):
      Revert "scsi: fcoe: clear FC_RP_STARTED flags when receiving a LOGO"
