Currently the i2c driver calls the pm_runtime_enable and never the disable. This may cause a warning when pm_runtime_enable checks for the count match.Attempting to fix the same by calling pm_runtime_disable in the error and the remove path.I remember seeing Felipe doing the reverse to musb here: http://marc.info/?l=linux-omap&m=132432610700952&w=2 so I'm confused here.Strange however ?I see many drivers doing the same in the kernel on greping . Besides I expect a warn to come up. Felipe could you explain the issue?
When do you see the warning? kfree(dev) should disable runtime pm, but without waking up the device. -- Felipe Contreras
