commit 765e40b6 upstream. The blk-mq code lacks support for looking at the rpm_status field, tracking active requests and the RQF_PM flag. Due to the default switch to blk-mq for scsi people start to run into suspend / resume issue due to this fact, so make sure we disable the runtime PM functionality until it is properly implemented.
