By always allocating and adding, respectively removing and freeing
the se_node_acl structure in core code we can remove tons of repeated
code in the init_nodeacl and drop_nodeacl routines. Additionally
this now respects the get_default_queue_depth method in this code
path as well.

USB3380 enhanced mode allows GPEP to be used in both IN and OUT
directions. However, IN and OUT endpoints must use same USB endpoint
address (bEndpointAddress). Fix this by setting the ep_cfg.ep_number

Originally FFS_FL_CALL_CLOSED_CALLBACK flag has been used to
indicate if we should call ffs_closed_callback().
Commit 4b187fceec3c ("usb: gadget: FunctionFS: add devices

call ffs_closed() function which does a little bit more.

if this flag is set.
Reproduction path:
Compile kernel without any UDC driver or bound some gadget
to existing one and then:
$ modprobe g_ffs
$ mount none -t functionfs mount_point
$ ffs-example mount_point
This will fail with -ENODEV as there is no udc.
$ ffs-example mount_point
This will fail with -EBUSY because ffs_data has not been

rndis_get_nr() returns either a non-negative value on success
or a negative value on failure. In case of failure an error code
is returned to the caller of rndis_register().
If the "i" is unsigned, the information about error from rndis_get_nr()
is lost. If there is no error but rndis_get_nr() returns a value greater
than 256 the least significant bits of i are zero effectively limiting the
number of configs to 256.

RNDIS function has a limitation on the number of allowed instances.
So far it has been RNDIS_MAX_CONFIGS, which happens to be one.
In order to eliminate this kind of arbitrary limitation we should not
preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params
instances but instead allow allocating them on demand.
This patch allocates struct rndis_params on demand in rndis_register().
Coversly, the structure is free()'d in rndis_deregister().
If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which
is the same behaviour as before, but the moment of creation is delayed
until struct rndis_params is actually allocated.
rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

RNDIS function has a limitation on the number of allowed instances.
So far it has been RNDIS_MAX_CONFIGS, which happens to be one.
In order to eliminate this kind of arbitrary limitation we should not
preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params
instances but instead allow allocating them on demand.
This patch prepares the elimination of the said limit by converting all the
functions which accept rndis config number to accept a pointer to the
actual struct rndis_params. Consequently, rndis_register() returns
a pointer to a corresponding struct rndis_params instance. The pointer
is then always used by f_rndis.c instead of config number when it talks
to rndis.c API.
A nice side-effect of the changes is that many lines of code in rndis.c
become shorter and fit in 80 columns.
If a function prototype changes in rndis.h a style cleanup is made
at the same time, otherwise checkpatch complains that the patch
has style problems.

A recent change introduced a link error for the composite
printer gadget driver:
`printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o
Evidently the unbind function should not be marked __exit here,
because it is called through a callback pointer that is not necessarily
discarded, __composite_unbind() is indeed called from the error path of
composite_bind(), which can never work for a built-in driver.
Looking at the surrounding code, I found the same problem in all other
composite gadget drivers in both the bind and unbind functions, as
well as the udc platform driver 'remove' functions. Those will break
if anyone uses the 'unbind' sysfs attribute to detach a device from a
built-in driver.
This patch removes the incorrect annotations from all the gadget
drivers.

When a single thread is sending out data over the gadget serial port,
gs_start_tx() will be called both from the sender context and from the
write completion. Since the port lock is released before the packet is
queued, the order in which the URBs are submitted is not guaranteed.
E.g.
sending thread completion (interrupt)
gs_write()
LOCK
gs_write_complete()
LOCK (wait)
gs_start_tx()
req1 = list_entry(pool->next)
UNLOCK
LOCK (acquired)
gs_start_tx()
req2 = list_entry(pool->next)
UNLOCK
usb_ep_queue(req2)
usb_ep_queue(req1)
I.e., req2 is submitted before req1 but it contains the data that
comes after req1.
To reproduce, use SMP with sending thread and completion pinned to
different CPUs, or use PREEMPT_RT, and add the following delay just
before the call to usb_ep_queue():
if (port->write_started > 0 && !list_empty(pool))
udelay(1000);
To work around this problem, make sure that only one thread is running
through the gs_start_tx() loop with an extra flag write_busy. Since
gs_start_tx() is always called with the port lock held, no further
synchronisation is needed. The original caller will continue through
the loop when the request was successfully submitted.

Most of kernel code assume that interface array in
struct usb_configuration is NULL terminated.
When gadget is composed with configfs configuration
structure may be reused for different functions set.
This bug happens because purge_configs_funcs() sets
only next_interface_id to 0. Interface array still
contains pointers to already freed interfaces. If in
second try we add less interfaces than earlier we
may access unallocated memory when trying to get
interface descriptors.

Instead of calling target_fabric_configfs_init() +
target_fabric_configfs_register() / target_fabric_configfs_deregister()
target_fabric_configfs_free() from every target driver, rewrite the API
so that we have simple register/unregister functions that operate on
a const operations vector.
This patch also fixes a memory leak in several target drivers. Several
target drivers namely called target_fabric_configfs_deregister()
without calling target_fabric_configfs_free().
A large part of this patch is based on earlier changes from
Bart Van Assche <bart.vanassche@sandisk.com>.

usb: patches for v4.1 merge window
As usual, a big pile of commits. This time a total
of 111 non-merge commits.
Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.
The printer gadget has been converted to configfs interface
