How about a pm_runtime_disable() here?
MX28 doesn't do runtime PM yet. Actually it doesn't do any PM.
I was probably misled by the call to pm_runtime_enable in your probe

:-( Then can we have it removed from probe as well?
Yes, either that or properly add runtime PM support since mxc maybe does support 
it, I dunno right now.
I think adding pm_runtime_disable() to the exit path should be the way
to go. proper callbacks can be implemented later, but we cannot leave pm
enabled for the device.
