Dave Penkler 6b3a2d6fd2 usb: usbtmc: Fix erroneous generic_read ioctl return 
commit 4e77d3ec7c upstream.

wait_event_interruptible_timeout returns a long
The return value was being assigned to an int causing an integer overflow
when the remaining jiffies > INT_MAX which resulted in random error
returns.

Use a long return value, converting to the int ioctl return only on error.
