Is there an 'easy' way to override the detected size of a storage

In the next commit, we will want the usb-common module to be composed of
two object files. Since Kbuild cannot "append" another object to an
existing one, we need to rename usb-common.c to something
else (common.c) and create usb-common.o by linking the wanted objects
together. Currently, usb-commo
All USB peripheral controller drivers called completion routines
directly. This patch moves the completion call from drivers to
usb_gadget_giveback_request(), in order to have a place where common
functionality can be added.
All places in drivers/usb/ matching "[-.]complete(" were replaced with a
This adds LED triggers for USB host and device. First patch refactors
UDC drivers as requested by Felipe Balbi, second is a preparation for
the third, which adds the LED triggers.
Changes from v4:
- Replaced BUG_ON with pr_err (Alan Stern, greg k-h).
- Used proper coding style for switch statemen
With this patch, USB activity can be signaled by blinking a LED. There
are two triggers, one for activity on USB host and one for USB gadget.
Both triggers should work with all host/device controllers. Tested only
with musb.

The UAC2 function driver currently responds to all packets at all times
with wMaxPacketSize packets. That results in way too fast audio
playback as the function driver (which is in fact supposed to define
the audio stream pace) delivers as fast as it can.
We need data rate to match, as accurately
