    I caught a couple conflicts with scsi.git/for-next and was able to fix
    them up without rebasing on top of your tree. I'll resend the series
    after letting these sit in -next for a while, or I can prepare a tag
    for you to pull with the whole pending set.

    dropped the include of async.h

    dropped the changes to scsi_wait_scan.c since that file is deleted in
    your for-next branch.
