Greg Kroah-Hartman b1f56acaca staging: usbip: use DEVICE_ATTR_RO/RW for sysfs attributes
It's easier to audit the sysfs files if they use the RO/RW macros, so
convert the usbip code to them.

Kurt Kanzenbach 70e90fb57f staging: usbip: userspace: show product name in `list -l' command
The `usbip list -l' command shows your local usb-devices.
Example:
 $ usbip list -l
 $ Local USB devices
 $ =================
 $ - busid 1-1 (13fe:1d00)
 $         1-1:1.0 -> usb-storage
 $
 $ - busid 1-2 (0409:55aa)
 $         1-2:1.0 -> hub

However this list command doesn't show which device is connected
to this busid. Therefore you have to use another tool e.g. lsusb
to determine that.

This patches adds the possibility to see which device that is.
Example:
 $ usbip list -l
 $ Local USB devices
 $ =================
 $ - busid 1-1 (13fe:1d00)
 $   Kingston Technology Company Inc. : DataTraveler 2.0 1GB/4GB Flash Drive / Patriot Xporter 4GB Flash
 $         1-1:1.0 -> usb-storage
 $
 $ - busid 1-2 (0409:55aa)
 $   NEC Corp. : Hub (0409:55aa)
 $         1-2:1.0 -> hub

If parsable is specified the info will be not printed.

Kurt Kanzenbach 80e4b9432c staging: usbip: userspace: unified command line arguments
The command `usbip attach' uses --host for specifing
the remote host, while `usbip list' uses --remote.
This is confusing and this patch adapts this.
In Addition changed the manpage and README accordingly.

Before:
 $ usbip attach --host <host> -b <busid>
 $ usbip list --remote <host>

Now:
 $ usbip attach --remote <host> -b <busid>
 $ usbip list --remote <host>

Kurt Kanzenbach b2e0228409 staging: usbip: userspace: libsrc: cleanup parsing
Since the names.c/names.h are taken from another project, some
functions which names.c provides aren't used by usbipd.
This patch fixes:
 - removed useless comments
 - unified debug/error messages by using the macros
   provided by usbip_common.h
 - removed unnused code

The code cleanup includes:
 - remove unused data structures
 - remove code to create them
 - remove code to access them

The file names.c is used to parse the `usb.ids' file. The parser
stores a lot of information about usb devices that is never used.

The `usb.ids' file has several sections. Some variables (like
`lasthut') store the ID of the current section, and those variables
are used to decide which section is currently being parsed (i.e. in
which data structure the current line will be  stored).

We removed the code to read those IDs because they are never used
anyway. We replaced them by the pseudo-ID `1' (instead of reading the
ID from the file) to indicate that the parser is in a section that
can be ignored. If the parser is in such a section, the current line
(which contains sub-items for this section) is discarded.
