From 4546527350c3c508554dff53e9086e9d3de0b97b Mon Sep 17 00:00:00 2001 From: Andrzej Pietrasiewicz Date: Tue, 1 Jul 2014 15:47:47 +0200 Subject: [PATCH] usb: gadget: f_rndis: fix interface id for OS descriptors f->os_desc_table[0].if_id is zero by default. If the actual id happens to be different then no Feature Descriptors will be returned to the host for this interface, so assign if_id as soon as it is known.
