like ucsi_glink that unregister/register the same UCSI\ninstance across remoteproc restart then try to create an already\nexisting debugfs directory and log:\n\n debugfs: 'pmic_glink.ucsi.0' already exists in 'ucsi'\n\nUnregister debugfs entries as part of ucsi_unregister(), and\nclear ucsi->debugfs after freeing it so repeated unregister\npaths remain safe."}], "lastModified":
