Hi,
The goal of this series is to remove a few global variables within

more as library and share across all gadgets. That is a longer way up

The direct user of the gadget driver (composite, dbgp, inode,
file_storage) keeps a global variable where it stores a pointer to
something which identifies the current instance from the time calling
usb_gadget_probe_driver() and later in its -bind() callback.
This patch passes the struct
I'm not going to swear here. The Android gadget includes composite.c
from the main tree and overwrites functions. This would still work if I
rename it and remove the const attribute but the problem rises again
once we stop including composite.c and use it as a library function.

This partly reverts 07a18bd7 (usb gadget: don't save bind callback in
