3.2.62-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Alex Deucher <[email protected]> commit f6be5e64500abbba44e191e1ca0f3366c7d0291b upstream. If there are error flags in the aux transaction return -EIO rather than -EBUSY. -EIO restarts the whole transaction while -EBUSY jus retries. Fixes problematic aux transfers.
