USB: serial core should respect driver requirements
This patch (as997) fixes a bug in the USB serial core. The core needs

At the same time, the patch changes the NUM_DONT_CARE constant (which

Fix a longstanding race in the Ethernet gadget driver, which can cause an

whether its freelist is empty. That check is otherwise not necessary,
since the queue is always stopped when that list empties (and restarted
when request completion puts an entry back on that freelist).
The race window starts when the network code decides to transmit a packet,
and ends when hard_start_xmit() grabs the freelist lock. When disconnect()
is called inside that window, it shuts down the TX queue and breaks the
otherwise-solid assumption that packets are never sent through a TX queue
that's stopped.

USB: fix errornous assumption in the usb serial framework revealed by iuu_phoenix
the iuu_phoenix driver submits another URB from a completion handler.
This dictates a certain order of calls to usb_kill_urb() in kill_traffic().
As other drivers may do it the other way round, we need to use both
orders in kill_traffic().

Currently the only way to distinguish these ports in userspace is by

USB: cleanups for g_file_storage
This patch (as957) makes some minor cleanups to the g_file_storage
driver:
Update the copyright date and version string;
Uniformize the logging macros for the gadget and the LUNs;
Remove "inline" markers -- nowadays we rely on the compiler
to decide which routines are best inlined;
Use the print_hex_dump() library routines;
Remove some unnecessary assignments within conditionals
and fix some close-brace indenting levels;
Fix some column-80 violations.
