From 35bfde36872607b1de87288f9798af79820a910f Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Wed, 16 Sep 2015 12:10:40 +0200 Subject: [PATCH] usb: gadget: f_ncm: obtain cdev from function instead of driver_data The 'driver_data' field in ep0 is never set to pointer to cdev, so we have to obtain it from another source as in this context ep->driver_data contains invalid data.
