These\nreferences are normally released by mhi_ep_destroy_device() before the\ndevice itself is removed.\n\nIf dev_set_name() or device_add() fails, the error path currently drops\nonly one reference. The remaining channel references keep the device\nfrom being released and leave the channels associated with a device that\nwas never registered.\n\nRoute both failures through a common unwind path that drops the DL\nchannel reference, the UL channel reference, and the initial reference\nfrom
