linux-toradex.git/drivers/usb/gadget/functions.c, branch v3.10.78 Linux kernel for Apalis and Colibri modules usb: gadget: add a forward pointer from usb_function to its "instance" 2013-01-21T18:52:46+00:00 Sebastian Andrzej Siewior bigeasy@linutronix.de 2012-12-23T20:10:15+00:00 0062f6e56f70bd2230ba1ebd1667d1b32a1af3b2 We can have multiple usb_functions which origin is the same "instance". Within one USB configuration there should be only one function of an instance. This back pointer helps configfs to recoginze to which instance a given usb_function belongs.
