> Fix the warning caused by enabling the autosectionlabel extension in the
> kernel Sphinx build:
> 
> Documentation/gpu/i915.rst:610: WARNING: duplicate label
> gpu/i915:layout, other instance in Documentation/gpu/i915.rst
> 
> In the warning message, Sphinx is unable to reference the labels in
> their true locations in the kernel-doc comments in source. In this case,
> there's "Layout" sections in both gt/intel_workarounds.c and
> i915_reg.h. Rename the section in the latter to "File Layout".
> 
> Fixes: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst")
