Sounds like this should get queued separately as a fix for v5.3-rc cycle, probably got broken with the recent ti-sysc init order changes. Regards, Tony

Yeah, this patch does not depend on the previous 4 patches, so can be picked up independently for v5.3-rc as well. regards Suman

OK applying the $subject patch into fixes, and the rest into omap-for-v5.4/ti-sysc. Regards, Tony

The clocks are not yet parsed and prepared until after a successful sysc_get_clocks(), so there is no need to unprepare the clocks upon any failure of any of the prior functions in sysc_probe(). The current code path would have been a no-op because of the clock validity checks within sysc_unprepare(), but let's just simplify the cleanup path by returning the error directly. While at this, also fix the cleanup path for a sysc_init_resets() failure which is executed after the clocks are prepared.
