When the return value type was changed from int to bool, few places
were left unchanged, this fixes them. We did not hit these failures as
the first one is not happening at all and the second one is little
more likely to happen if the user switches a 33..58bit DMA capable
device between the VFIO and vendor drivers and there are not so many
of these.

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.
