usb: gadget: nokia: fix error recovery path for optional functions
In the nokia gadget some USB functions (obex 1 and 2, phonet) are optional.
If at the start of nokia_bind_config e.g. fi_phonet is an error pointer,
which can happen because we don't fail the bind process if
usb_get_function_instance() fails for fi_phonet, then f_phonet is NULL, and
phonet_stat = usb_add_function(c, f_phonet);
is never called and phonet_stat remains 0.
If, in these circumstances, we hit the err_conf label then !phonet_stat
evaluates to true and we try usb_remove_function() with its second
parameter being f_phonet which is NULL and it causes NULL pointer
dereference.
This patch changes the initial values of (obex1|obex2|phonet)_stat to a
nonzero value so that if the err_conf label is hit while the respective
functions have not been acquired the usb_remove_function() is not called
for those functions.

The use of variable length arrays in structs (VLAIS) in the Linux Kernel code
precludes the use of compilers which don't implement VLAIS (for instance the

memory buffer using macros. The previous patch required multiple kmalloc and

usb: gadget: configfs: allow setting function instance's name
USB function's configfs config group is created in a generic way in
usb/gadget/configfs.c:function_make(), which in turn delegates actual
allocation and setup of the USB function instance to a particular
implementation, e.g. in f_acm.c. The said implementation does its job
in a parameter-less function e.g. acm_alloc_instance(), which results
in creating an unnamed config group, whose name is set later in
function_make(). function_make() creates the name by parsing a string
of the form:
<function name>.<instance name>
which comes from userspace as a parameter to mkdir invocation.
Up to now only <function name> has been used, while <instance name>
has been ignored. This patch adds a set_inst_name() operation to
struct usb_function_instance which allows passing the <instance name>
from function_make() so that it is not ignored. It is entirely up to the
implementor of set_inst_name() what to do with the <instance name>.
In a typical case, the struct usb_function_instance is embedded in a
larger struct which is retrieved in set_inst_name() with container_of(),
and the larger struct contains a field to store the <instance name>.

This behavior is required to provide equivalent of gadget zero with configfs.
The gadget zero has a "config driver" for sourcesink, but all it does is

usb: gadget: f_mass_storage: make sysfs interface optional
When configfs is in place, the luns will not be represented in sysfs,
so there will be no struct device associated with a lun.
In order to maintain compatibility and allow configfs adoption
sysfs is made optional in this patch.
As a consequence some debug macros need to be adjusted. Two new
fields are added to struct fsg_lun: name and name_pfx.
The "name" is for storing a string which is presented to the user
instead of the dev_name. The "name_pfx", if non-NULL, is prepended
to the "name" at printing time.
The name_pfx is for a future lun.0, which will be a default group in
mass_storage.<name>. By design at USB function configfs group's creation
time its name is not known (but instead set a bit later in
drivers/usb/gadget/configfs.c:function_make) and it is this name that
serves the purpose of the said name prefix. So instead of copying
a yet-unknown string a pointer to it is stored in struct fsg_lun.

usb: gadget: f_mass_storage: add a level of indirection for luns storage
This is needed to prepare for configfs integration.
So far the luns have been allocated during gadget's initialization, based
on the nluns module parameter's value; the exact number is known when the
gadget is initialized and that number of luns is allocated in one go; they
all will be used.
When configfs is in place, the luns will be created one-by-one by the user.
Once the user is satisfied with the number of luns, they activate the
gadget. The number of luns must be <= FSG_MAX_LUN (currently 8), but other
than that it is not known up front and the user need not use contiguous
numbering (apart from the default lun #0). On the other hand, the function
code uses lun numbers to identify them and the number needs to be used
as an index into an array.
Given the above, an array needs to be allocated, but it might happen that
7 out of its 8 elements will not be used. On my machine
sizeof(struct fsg_lun) == 462, so > 3k of memory is allocated but not used
in the worst case.
By adding another level of indirection (allocating an array of pointers
to struct fsg_lun and then allocating individual luns instead of an array
of struct fsg_luns) at most 7 pointers are wasted, which is much less.
This patch also changes some for/while loops to cope with the fact
that in the luns array some entries are potentially empty.

USB descriptors are exported so that they can be accessed from

Handling of CONFIG_USB_GADGET_DEBUG_FILES is moved to f_mass_storage.c.

Split uImage on "clean" uImage and Device Tree blob.
1. The change is due to upgrade u-boot to latest upstream version
which support separate uImage and DTB.
Addtionally current defult u-boot configuration for trats2 assumes
that kernel image and DTB are delivered as separat files.
2. DTB files are located in /boot directory.
3. Together with uImage are delivered all DTBs which are compatible with
tizen_defconfig kernel configuration.
