drm/amd/amdxcp: Fix warnings
Lijo Lazar authored
Range of possible values of pdev_num is 0-63. Use int8_t as data type.
That also fixes below warnings:

>> drivers/gpu/drm/amd/amdxcp/amdgpu_xcp_drv.c:59:58: warning: '%d'
>> directive output may be truncated writing between 1 and 11 bytes into
>> a region of size 9 [-Wformat-truncation=]
      59 |         snprintf(dev_name, sizeof(dev_name), "amdgpu_xcp_%d", pdev_num);
         |                                                          ^~

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 reStructuredText 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.
