This is due to the missing include of linux/usb/composite.h - this patch
adds the missing include.

In addition there's also a problem in fsg_common_init() where we memset
'common', but we use the size of a pointer to 'struct fsg_common' as the
size argument to memset(), not the actual size of the struct. This patch
fixes the sizeof so we zero the entire struct as intended.

      USB: fix race between root-hub resume and wakeup requests · bf3d7d40
      Alan Stern authored 
      The USB core keeps track of pending resume requests for root hubs, in
order to resolve races between wakeup requests and suspends.  However
the code that does this is subject to another race (between wakeup
requests and resumes) because the WAKEUP_PENDING flag is cleared
before the resume occurs, leaving a window in which another wakeup
request might arrive.

This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING
flag after the resume instead of before it.

This fixes Bugzilla #24952.

      USB: prevent buggy hubs from crashing the USB stack · d199c96d
      Alan Stern authored 
      If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash.  This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

      USB SL811HS HCD: Fix memory leak in sl811h_urb_enqueue() · 2bd15f1f
      Jesper Juhl authored 
      In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
without having been assigned to anything, so we'll leak the memory we
allocated.
This patch fixes the leak by simply calling kfree(ep); before jumping to
the 'fail' label.

      USB: io_edgeport: fix the reported firmware major and minor · 271c1150
      Bjørn Mork authored 
      The major and minor number saved in the product_info structure
were copied from the address instead of the data, causing an
inconsistency in the reported versions during firmware loading:

 usb 4-1: firmware: requesting edgeport/down.fw
 /usr/src/linux/drivers/usb/serial/io_edgeport.c: downloading firmware version (930) 1.16.4
 [..]
 /usr/src/linux/drivers/usb/serial/io_edgeport.c: edge_startup - time 3 4328191260
 /usr/src/linux/drivers/usb/serial/io_edgeport.c:   FirmwareMajorVersion  0.0.4

This can cause some confusion whether firmware loaded successfully
or not.
