From: Hannes Reinecke Date: Fri, 28 Feb 2020 07:53:08 +0000 (+0100) Subject: scsi: dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commands X-Git-Tag: v5.10.7~2825^2~158 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=84ff9532e5308d04f97f032a434021ba1b01b6a3;p=platform%2Fkernel%2Flinux-rpi.git scsi: dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commands Rather than traversing all outstanding commands manually, use the scsi_host_complete_all_commands() helper to terminate all commands during reset. With that we can drop the cmd_list usage from the midlayer.
