Dave Penkler 8d9a5eaeed usb: usbtmc: Fix erroneous get_stb ioctl error returns
commit cac01bd178d6a2a23727f138d647ce1a0e8a73a1 upstream.

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

Use a long return value and convert to int ioctl return only on error.

When the return value of wait_event_interruptible_timeout was <= INT_MAX
the number of remaining jiffies was returned which has no meaning for the
user. Return 0 on success.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
