Hi Tony,

Please find couple of non-urgent fixes to the OMAP dmtimer driver.
The patches are based on 4.0-rc1.

The first patch is a fix for the issue I reported earlier on the
DRA7 dmtimer hwmod patches [1]. DRA7 has timers 13 through 16 disabled
in DT currently, and enabling any of them would cause a kernel hang.
This fix properly checks the pm_runtime_get_sync() calls in the OMAP
dmtimer driver irrespective of whether the hwmods are added or not.
In the case that they are not added, the runtime_pm calls should return
the value as returned from _od_fail_runtime_resume(), and the probe
should bail out properly fixing the boot hang.

Second patch is a minor fix that balances the pm_runtime_enable() call
in probe with pm_runtime_disable() call in remove, so that the devices
can be bound again properly after doing an unbind through sysfs.
