[GIT PULL] SCSI fixes for 5.1-rc5

From: James Bottomley
Date: Sat Apr 20 2019 - 15:05:11 EST


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"
