Linux kernel source tree
3206a96675
When CONFIG_DEBUG_FS is disabled, the stid_fmts[] array is not referenced
anywhere, causing a W=1 warning with gcc:
In file included from drivers/gpu/drm/imagination/pvr_fw_trace.c:7:
drivers/gpu/drm/imagination/pvr_rogue_fwif_sf.h:75:39: error: 'stid_fmts' defined but not used [-Werror=unused-const-variable=]
75 | static const struct rogue_km_stid_fmt stid_fmts[] = {
| ^~~~~~~~~
Rather than adding more #ifdef blocks, address this by changing the
existing #ifdef into equivalent IS_ENABLED() checks so gcc can see
where the symbol is used but still eliminate it from the object file.

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.
