Kernel panic is seen during device boot. It appears that before the
probe completes, runtime callbacks happen and the device setup is not
done yet. This could be initiated from framework through exposed
callbacks. This issue can be fixed by having a flag to indicate
completion of device probe. Hence 'probed' flag is introduced to notify
completion of probe and runtime callbacks can check this flag before
doing any device access.
Such a fix should be rather folded into the previous, especially if
you know it's already broken :)
Ok, I will meld this with previous commit.
And, IMO, it's better to put such a check into runtime_idle callback
instead of doing in each (runtime_)suspend/resume callback.
Check in runtime_idle would take care of suspend path. But how the check in
runtime_resume can be avoided? Kernel panic happened during
runtime_resume().
thanks,
