Tomi Valkeinen 5025ce070e OMAPDSS: fix bogus WARN_ON in dss_runtime_put()
pm_runtime_put_sync() in dss_runtime_put() returns -EBUSY when any child
of dss is still enabled. This happens, for example, when a display
output is enabled and one dumps the clocks via debugfs. This causes
dss_runtime_get & put to be called.

While I couldn't find anything about this in the documentation and it
wasn't immediately clear from runtime_pm code, it looks to me that
pm_runtime_put_sync() returns -EBUSY to inform that things went fine,
but the device could not be turned off as there are still child devices
that are enabled. This is not a problem.

This patch skips the WARN_ON if pm_runtime_put_sync() returns -EBUSY.
