An effort is\nunder way to get GLINK to invoke its callbacks in a sleepable context,\nbut until then lets schedule the unregistration.\n\nA side effect of this is that ucsi_unregister() can now happen\nafter the remote processor, and thereby the communication link with it, is\ngone. pmic_glink_send() is amended with a check to avoid the resulting NULL\npointer dereference.\nThis does however result in the user being informed about this error by\nthe following entry in the kernel log:\n\n  ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI write request: -5"
