Subject: [SCSI] cleanup usages of scsi_complete_async_scans
X-Git-Tag: v3.6-rc1~103^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=492d542273a4859f8bf8cc7744cdf71ef50b39ea;p=platform%2Fkernel%2Flinux-stable.git

[SCSI] cleanup usages of scsi_complete_async_scans

Now that scsi registers its async scan work with the async subsystem,
wait_for_device_probe() is sufficient for ensuring all scanning is
complete.

[jejb: fix merge problems with eea03c20ae38 Make wait_for_device_probe() also do scsi_complete_async_scans()]
