Recently we landed 03de19212ea3 ("mmc: dw_mmc: introduce timer for broken command transfer over scheme"). 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.
Changes in v2: - Removed extra "int i" - Fix the DTO timeout calculation new for v2 - Cleanup the DTO timer new for v2
