Pull USB fixes from Greg KH:
 "Here are a number of small USB driver fixes for 4.9-rc3.

  There is the usual number of gadget and xhci patches in here to
  resolved reported issues, as well as some usb-serial driver fixes and
  new device ids.

  All have been in linux-next with no reported issues"

* The pointer is initialised with NULL value and may be set by
* __ffs_epfile_read_data function to point to a temporary buffer.
*
* In normal operation, calls to __ffs_epfile_read_buffered will consume
* data from said buffer and eventually free it. Importantly, while the
* function is using the buffer, it sets the pointer to NULL. This is
* all right since __ffs_epfile_read_data and __ffs_epfile_read_buffered
* can never run concurrently (they are synchronised by epfile->mutex)
* so the latter will not assign a new value to the pointer.
*
* Meanwhile ffs_func_eps_disable frees the buffer (if the pointer is
* valid) and sets the pointer to READ_BUFFER_DROP value. This special
* value is crux of the synchronisation between ffs_func_eps_disable and
* __ffs_epfile_read_data.
*
* Once __ffs_epfile_read_data is about to finish it will try to set the
* pointer back to its old value (as described above), but seeing as the
* pointer is not-NULL (namely READ_BUFFER_DROP) it will instead free
