Up to now, when endpoint addresses in descriptors were non-consecutive,
there were created redundant files, which could cause problems in kernel,
when user tried to read/write to them. It was result of fact that maximum
endpoint address was taken as total number of endpoints in function.
This patch adds endpoint descriptors counting and storing their addresses
in eps_addrmap to verify their cohesion in each speed.
Endpoint address map would be also useful for further features, just like
vitual endpoint address mapping.

Clearly this was meant to be an include guard, but a trailing
underscore was missing. It has been this way since the file was
introduced in 0fe6f1d1 ("usb: udc: add Faraday fusb300 driver").

The variable $(PWD) is useless, and it may break the compilation.

This reverts commit a9232076374334ca2bc2a448dfde96d38a54349a.
It introduced a dead lock, and did not fix anything.
it made netif_tx_lock() be called in IRQ context, but in softirq context,
the same lock is locked without disabling IRQ. In fact, the commit a923207637
did not fix anything, since netif_stop_queue did not free the any resource

After dbgp_bind()-dbgp_unbind() cycle happens, static variable dbgp
contains pointers to already deallocated memory (dbgp.serial and dbgp.req).
If the next dbgp_bind() fails, for example in usb_ep_alloc_request(),
dbgp_bind() calls dbgp_unbind() on failure path,
and dbgp_unbind() frees dbgp.serial that still stores a pointer
to already deallocated memory.
The patch sets pointers to NULL in dbgp_unbind().

3) Take advantage of hash table in UDP multicast delivery, from David

5) Add support for various RFC6458 control messages in SCTP, from
Geir Ola Vaagland.
6) Allow to filter bridge forwarding database dumps by device, from
Jamal Hadi Salim.
7) virtio-net also now supports busy polling, from Jason Wang.
8) Some low level optimization tweaks in pktgen from Jesper Dangaard
Brouer.
9) Add support for ipv6 address generation modes, so that userland
can have some input into the process. From Jiri Pirko.
10) Consolidate common TCP connection request code in ipv4 and ipv6,
from Octavian Purdila.
11) New ARP packet logger in netfilter, from Pablo Neira Ayuso.
12) Generic resizable RCU hash table, with intial users in netlink and
nftables. From Thomas Graf.
13) Maintain a name assignment type so that userspace can see where a
network device name came from (enumerated by kernel, assigned
explicitly by userspace, etc.) From Tom Gundersen.
14) Automatic flow label generation on transmit in ipv6, from Tom
Herbert.
15) New packet timestamping facilities from Willem de Bruijn, meant to
assist in measuring latencies going into/out-of the packet
scheduler, latency from TCP data transmission to ACK, etc"

usb: patches for v3.17 merge window
Surprisingly enough, while a big set of patches, the majority is
composed of cleanups (using devm_*, fixing sparse errors, moving
code around, adding const, etc).
The highlights are addition of new support for PLX USB338x devices,
and support for USB 2.0-only configurations of the DWC3 IP core.

This fixes a problem with dropped packets over 16k CDC-NCM
when the connection is being heavily used.
The issue was that the extracted frames cloned from the
received frame were consuming more memory than necessary
resulting in the truesize being ~32KB instead of ~2KB, this
meant there was a high chance of reaching the sk_rcvbuf
limit.

This adds multi-frame support to the NCM NTB's for
the gadget driver. This allows multiple network
packets to be put inside a single USB NTB with a
maximum size of 16kB.
It has a time out of 300ms to ensure that smaller
number of packets still maintain a normal latency.
Also the .fp_index and .next_fp_index have been
changed to .ndp_index and .next_ndp_index to
match the latest CDC-NCM specification and
help with maintenance.
Results transmitting from gadget to host.

means that NTBs containing multiple NDPs would have missed

Add support for OS descriptors. The new format of descriptors is used,
because the "flags" field is required for extensions. os_count gives
the number of OSDesc[] elements.
The format of descriptors is given in include/uapi/linux/usb/functionfs.h.
For extended properties descriptor the usb_ext_prop_desc structure covers
only a part of a descriptor, because the wPropertyNameLength is unknown
up front.

ffs_do_desc() handles one descriptor, while ffs_do_descs() handles a number
of descriptors. The tho names are so similar that it causes confusion.
Rename to reflect their purpose better.

commit c63d2225e7be ("usb: gadget: pxa25x_udc: use devm_ functions")
introduced the use of devm_gpio_request in this driver, but did not
correctly include the header file declaring this function, which
causes a build failure.
This changes pxa25x_udc to include linux/gpio.h instead of asm/gpio.h
to fix this.

Syscall mount returns -ENODEV error if requested FS type
has not been found. Returning the same error from FFS mount
callback makes value returned to userspace misleading.
Other file systems returns -ENOENT if requested device
has not been found. Adjust FFS to this convention to make
error codes meaningfull.
