The patch applied with no problems, but there's a compile error in scsi_pm.c. Is there maybe a prereq patch we need?
I tried it against the latest from https://github.com/torvalds/linux (4.17.0_rc5+) as well as one of our internal test kernels (based on 4.17.0_rc1+), and both resulted in the same failure.

Here's the error:
