Hello Ching,

I applied both your series to 4.5/scsi-queue.

In the future please run checkpatch before submitting. Warnings are OK
but in this case there were several things flagged as errors that I had
to fix up by hand.

Also make sure you tag with "Signed-off-by:". Your signoff was mistyped
in all the patches.

Thank you!
Martin
