[PATCH 0/3] cxl: documentation fixes

[Bagas Sanjaya]

Building htmldocs on next-20220803 (for which this series is based on),
there are new warnings on cxl subsystem. The fixes below are
self-explanatory.

Bagas Sanjaya (3):
  cxl/regions: add padding for cxl_rr_ep_add nested lists
  cxl/region: describe targets and nr_targets members of
    cxl_region_params
  Documentation: cxl: remove dangling kernel-doc reference

[PATCH 1/3] cxl/regions: add padding for cxl_rr_ep_add nested lists

[Bagas Sanjaya]

Sphinx reported indentation warnings:

Documentation/driver-api/cxl/memory-devices:457: ./drivers/cxl/core/region.c:732: WARNING: Unexpected indentation.
Documentation/driver-api/cxl/memory-devices:457: ./drivers/cxl/core/region.c:733: WARNING: Block quote ends without a blank line; unexpected unindent.
Documentation/driver-api/cxl/memory-devices:457: ./drivers/cxl/core/region.c:735: WARNING: Unexpected indentation.

These warnings above are due to missing blank line padding in the nested list
in kernel-doc comment for cxl_rr_ep_add().

Add the paddings to fix the warnings.

[PATCH 2/3] cxl/region: describe targets and nr_targets members of cxl_region_params

[Bagas Sanjaya]

Sphinx reported undescribed parameters in cxl_region_params struct:

./drivers/cxl/cxl.h:376: warning: Function parameter or member 'targets' not described in 'cxl_region_params'
./drivers/cxl/cxl.h:376: warning: Function parameter or member 'nr_targets' not described in 'cxl_region_params'

Describe these members.

[PATCH 3/3] Documentation: cxl: remove dangling kernel-doc reference

[Bagas Sanjaya]

Sphinx reported kernel-doc failure warning, pointing to non-existent
drivers/cxl/region.h (which doesn't also exist throughout repo history):

WARNING: kernel-doc './scripts/kernel-doc -rst -enable-lineno -sphinx-version 2.4.4 -no-doc-sections ./drivers/cxl/region.h' failed with return code 1

Above cause error message to be displayed on htmldocs output.

Delete the reference.

Looks right to me.  Sphinx white space around lists is annoyingly fiddly but
such is life.

Ah. That went in some refactoring along the way.

That seems unlikely to be right tag. Probably b9686e8c8e39

With that tidied up.

Thanks, applied, and with Jonathan's Fixes: tag fixup.
