I see that my changelog is very cryptic. Sorry about that.
I have been converting drivers from using legacy pm_ops to dev_pm_ops which will allow all drivers to use the same infrastructure and overtime obsolete the legacy usage. With this change I made, __device_suspend() will find dev->bus->pm->suspend instead of dev->bus->suspend.
isa bus and isa drivers probably will never take advantage of the pm capabilities dev_pm_ops allow for, the reason to update the isa bus to use dev_pm_ops is to allow for obsoleting legacy pm_ops handling in pm.
