Commitb0a2ee5567("drm/xe: prepare xe_gen_wa_oob to be multi-use") introduced a call to basename(). The GNU version of this function is not portable and fails to build with alternative libc implementations like musl or bionic. This causes the following build error: drivers/gpu/drm/xe/xe_gen_wa_oob.c:130:12: error: assignment to ‘const char *’ from ‘int’ makes pointer from integer without a cast [-Wint-conversion] 130 | fn = basename(fn); | ^ While a POSIX version of basename() could be used, it would require a separate header plus the behavior differs from GNU version in that it might modify its argument. Not great. Instead, implement a local xbasename() helper based on strrchr() that provides the same functionality and avoids portability issues.

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.
