Using a `char` to fit a CPU index is too small, and assigning -1 to it isn't correct either, since `char` is sometimes signed and sometimes not. In this case, it's been fine since this driver only works on sparc, but that will soon be changing when chars become unsigned everywhere. So instead, use a normal `int` type, which matches the `int cpu` function argument that this is being compared against. Cc: David S. Miller <davem@davemloft.net> Signed-off-by: Jason A.

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.
