I found a bunch of problems with that patch, so this series attempts to solve some of them. This also fixes the DTO timer in some of the same ways even though I haven't personally seen problems with the DTO timer. NOTE: this series has only been lighly tested so far. I can at least reproduce the need for the CTO timer on one of my devices and so I can confirm that part still works. As mentioned in the 3rd patch I also ran the mmc_test kernel module on this and did manage to see the 3rd patch doing something useful.

I can add ack/drop patches for yet a couple of days this week.
Patch 4 introduce a warning: warning: unused variable ‘irqflags’ [-Wunused-variable] irqflags should be introduced in patch 5 in the same place. As it seems patch 5 will be candidate for 4.15, so could you please help fix patch 4 and 5 manually? Or Doug need to resend patch 4 and 5?
