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. -- Shuah Shuah Khan, Linux Kernel Developer - Open Source Group Samsung Research America (Silicon Valley) shuah.kh@...sung.com | (970) 672-0658 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
