From 4f06717fb063ad4ef38bd5e0ec1881bc784c325b Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 7 Mar 2018 10:46:57 +0100 Subject: [PATCH] net: kalmia: clean up bind error path Drop bogus call to usb_driver_release_interface() from an error path in the usbnet bind() callback, which is called during interface probe. At this point the interface is not bound and usb_driver_release_interface() returns early. Also remove the bogus call to clear the interface data, which is owned by the usbnet driver and would not even have been set by the time bind() is called.
