Hi,
patch6/7/8/9 are for handling of exception handling in probe() function.
Actually, I'm not sure that there are special reason to split out
the patches. I think that you can squash patch6/7/8/9 to only one patch.
Also, even if patch6/7/8/9 handle the exception handling in probe(),
the tegra_devfreq_probe() doesn't support the restoring sequence
when fail happen. I think that if you want to fix the fail case of probe(),
please add the restoring sequence about following function.
- clk_disable_unprepare()
- clk_notifier_unregister()
- dev_pm_opp_remove()
