The low-level Falcon bootstrapping callbacks are expected to return 0 on
success or a negative error code on failure. However, the implementation
on Tegra returns the ID or mask of the Falcons that were bootstrapped on
success, thus breaking the calling code, which treats this as failure.
Fix this by making sure we only return 0 or a negative error code, just
like the code for discrete GPUs does.

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.
