From 25fbf96b24fd3fe0a5252c374b445be32f42b0c8 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Thu, 1 May 2014 15:45:16 -0600 Subject: [PATCH] USB: gadget: save driver name before registering it g_dnl_register() currently first attempts to register a composite driver by name, and then saves the driver name once it's registered. Internally to the registration code, g_dnl_do_config() is called and attempts to compare the composite device's name with the list of known device names. This fails since the composite device's name has not yet been stored. This means that the first time "ums 0 0" is run, it fails, but subsequent attempts succeed. Re-order the name-saving and registration code to solve this.
