a92b63e7e4 USB: usbtmc: fix switch statment
Steve Holland pointed out that we forgot to call break; in the switch
statment.  This probably resolves a lot of the bug reports I've gotten
for the driver lately.

Stupid me...

228dd05dbf USB: usbtmc: add protocol 1 support
The driver already supports the 1 protocol support, so just add it to
the MODULE_DEVICE_TABLE entry so it properly picks up these devices.

Thanks to Jouni Rynö for pointing this out.

5b10916ea0 USB: usbtmc: fix stupid bug in open()
open() will never succeed, as we always return -ENODEV.  Fix this
obvious bug.

Thanks to Jouni Ryno for reporting it.

857cc4dfb6 USB: usbtmc: indent & braces disagree, something else is desired
It seems that there's rather involved way to say something
which is commonly written in a plain simple form.

Some type changes would probably be necessary to get gcc
to do bitops instead of divide but it's no worse after my
change than before I think.

5413aa4678 USB: fix problem with usbtmc driver not loading properly
The usbtmc driver forgot to export its device table to userspace.
Without this, it is never loaded properly when such a device is seen by
the system.

b361a6e348 USB: usbtmc: Use explicit unsigned type for input buffer instead of char*
Silences compiler warning about comparison with 0x80, and type now matches the
corresponding _bulk_out function.

drivers/usb/class/usbtmc.c: In function ‘usbtmc_ioctl_abort_bulk_in’:
drivers/usb/class/usbtmc.c:163: warning: comparison is always false due to limited range of data type

up this driver.
